Abstract:

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
NEW YORK UNIVERSITY
O artista norte-americano Robert Morris é conhecido sobretudo como escultor, mas sua obra abrange uma diversidade de meios, procedimentos e materiais, dentre os quais a dança. Morris esteve diretamente envolvido com grupos de dança entre o final da década de 1950 e meados da década de 1960, período em que participou do que foram talvez os dois mais importantes focos de pesquisa em dança, nos Estados Unidos, para a sua geração: as atividades que se desenvolveram em São Francisco, ao redor da professora e dançarina Ann Halprin, e as atividades que, em Nova York, resultaram da formação do grupo Judson Dance Theater. Nesse período, além de atuar como dançarino em trabalhos de outros artistas, Morris criou um pequeno mas significativo conjunto de trabalhos de dança. A tese toma esse conjunto como base para um estudo da obra do artista e procura vê- la, em grande parte, como desdobramento de experiências e questões surgidas no âmbito da dança, em diálogo com o seu concomitante envolvimento na pintura, no desenho e na escultura. Discutindo alguns dos pontos principais desse diálogo - como o reducionismo minimalista, os procedimentos de tarefa e instruções, a ênfase na temporalidade e na literalidade da ação corporal - e alguns de seus conceitos centrais - como estado de dança, forma vazia e anti-forma - , a tese se propõe a ampliar as possibilidades de análise e compreensão de um momento crucial não só para a formação e o curso subseqüente da obra de Morris, mas também para a constituição do campo ampliado da arte contemporânea.
The North American artist Robert Morris is known mostly as a sculptor, but his work encloses a diversity of means, procedures and materials among which dance. Morris was directly involved with dance groups between the end of the decade of 1950 until mid 1960, period in which he participated in what were maybe the two most important focuses of research in dance, in the United States, for his generation: the activities that were developed in San Francisco related to the professor and dancer Ann Halprin, and activities in New York City resulting from the formation of the group Judson Dance Theater. In this period, aside of acting as dancer in works from other artists, Morris created a small but significant set of dance works. The thesis considers this set as the basis for the study of the artist work and strives to see it, mainly, as a deployment of the experiences and questions arisen in the scope of dance, in dialogue with his concomitant involvement in painting, drawing and sculpture. Discussing some of the main points in this dialogue - as the minimalist reductionism, the procedures of tasks and instructions, the emphasis in the temporality and in the literality of the corporal action - and some of its central concepts - such as dance state, blank form and anti form - the thesis intends to extend the possibilities of analysis and comprehension of a crucial moment not only for the formation and the subsequent course of Morris work but also for the constitution of the expanded field of contemporary art.

Abstract:

We consider the problem of robustness, in particular that of robust stability. Such a problem is amenable to analysis by frequency domain techniques, and also using state space methods. Using some recent state space theory yielding the exact radius of the ball around a nominally stable system within which all additive perturbations retain stability, we show how control action may be implemented to increase the radius of this ball. We present further some material on how destabilizing perturbations may be constructed from solutions of Riccati equations, and how the above mentioned radii may be found with respect to an alternative norm to the one used above. Finally we give some remarks on the use of Lyapunov functions for systems.

Full text

Abstract:

The neo-Gramscian perspective, inspired by Robert Cox, has been in the forefront of developments in critical International Relations theory since the early-1980s. Derived from the historicist tradition in social science, including the work of Gramsci, Cox's method of historical structures - which comprise ideas. material capabilities, and institutions - challenged the positivism and trans-historical essentialisation of state power characteristic of traditional IR. Extending the method of historical structures to the understanding of the international system, Cox elaborated a triadic model of that system which comprised the mutual interactions between social forces engendered in production, forms of state, and world orders. This approach enabled Cox to develop a more sophisticated and comprehensive analysis of international change than that offered by the narrow state-centrism of traditionallR. Framing his approach within an interpretation of key ideas drawn from Gramsci's The Prison Notebooks, Cox created a space for the discussion of Marxist ideas in IR, previously largely resistant to Marxism. Cox, however, does not consider himself a Marxist and rejects important elements of Marxist theory. The critique of Cox and the neo-Gramscians that I develop in this thesis is based on a Marxist approach to social scientific explanation, and more specifically on the state capitalist perspective whose founder, Tony Cliff, conceived it as a return to classical Marxism, which the dominant versions of Marxism in the mid-twentieth century had, he argued, abandoned. The state capitalist perspective, developed as an attempt to understand the novel phenomenon of Stalinism in the USSR and its satellites, is mobilised throughout the thesis. Firstly against Cox's criticism that a focus on the fundamental relations of the mode of production leads to static and ahistorical analysis and, more widely, against his prioritisation of the role of ideas in shaping world orders. In particular, the Gramscian concept of hegemony, central to the neo-Gramscian perspective, IS criticised as providing an inadequate, and idealist, understanding of periods of relative social and political stability, which are explained instead by reference to the coercive aspects, broadly defined, of capitalism's dominant social relations. Coercion has been central to the imperialist structuring of the modern world system and, I argue, the concepts of imperialism and inter-imperialist rivalry retain their explanatory power even in what the neo-Gramscians refer to as the contemporary ·transnationalist' era

Full text

Abstract:

Robert Wilson has been a major figure on the international arts scene for close to half a century. Whether re-imagining canonic works of theater, staging operas, crafting newly-conceived multimedial productions, or advising Lady Gaga's performance at the 2013 MI 'V Awards, his instantly recognizable visual style has led his work to be called a "theater of images." Indeed, the world of Wilson scholarship has always been image-centered, at the expense of other key elements of the director's theatrical imagination—especially music and sound. Both of the latter, however, have long played a crucial role in Wilson's work. Though he is best known, in musical circles, for Einstein on the Beach (the opera he created in 1976 with Philip Glass and Lucinda Childs), Wilson has collaborated with musicians from the highest echelons of both popular and classical music. Furthermore, over the last several decades, he has developed a palette of sonic techniques in his theatrical productions that are no less recognizable than his stage designs.

This dissertation offers the first in-depth analysis of sound and music in Wilson's theatrical productions. Through analyses of live performances, production paratexts (including criticism and programs), archival materials, and conversations with Wilson and his collaborators, it harnesses Wilson's audio-visual language to develop an interdisciplinary framework for understanding sonic media in a theatrical context. Approaching "sound" as a broad concept that encompasses all elements of a production designed to be heard—music and songs, spoken text, and sound effects—I focus on Wilson's theatrical productions where these sonic elements exist in a state of parity. Since live performances provide the bedrock of my analyses, the methodological roots of this dissertation lie in the performance-based scholarship of opera and theater studies. These fields are brought into extensive dialogue with literature, visual art, architecture, performance studies, semiotics, and sociology, as well as interdisciplinary discourses such as media and sound studies. Wilson actively avoids sounds that "illustrate" his visuals, and images that "decorate" sounds, and through this assemblage of theoretical perspectives I demonstrate that neither his images nor his sounds can be adequately understood without the other.

My starting point is Wilson's oft-stated belief that properly structured images may help us "hear better," and that carefully deployed sounds may similarly help an audience "see better." Following the introduction, which surveys the existing literature on Wilson's work and establishes the aims, claims, and methodology of the dissertation, the first chapter examines this idea as both aesthetic tenet and practical directive. Chapter One also provides a brief overview of Wilson's history as a theater practitioner and consumer, and outlines the many influences on his current work. Chapter Two, the first of four analytic chapters, considers a sound that we are acculturated to filter out while listening: the crackling of a record. It examines how this sound, elevated to a level of sonic prominence, creates ambiguity about a sound's source while engaging the divergent performance histories of a particular song (the "Moritat" from Die Dreigroschenoper) and the space of its performance. Chapter Three explores Wilson's frequent use of sounds to represent objects which are not present onstage—specifically coins and doors. Built on a foundation of semiotic theory, this chapter crafts a new understanding of audio-visual communication in the theater through recourse to scholarship on sound, gesture, and architecture. Chapter Four adopts the concept of framing (as employed in art history and literary theory), and uses it to excavate how incidental music may enable material from "inside" the performance (characters, music) to intersect and interact with material from "outside" the performance (the audience, the auditorium). In particular, it considers how music creates a time and space where characters may step out of the narrative frame while still remaining inside the diegesis. Finally, Chapter Five focuses on Wilson's production Lulu, examining how interpolated songs (by Lou Reed) disrupt the teleological flow of a canonical story by engaging intertextual experiences and forging new musical memories within the space of the production.

Like performance itself, music and sound are ephemeral. As scholarship expands to engage live performance as an object of study, this dissertation offers a methodology for incorporating sonic elements into this vital scholarly discourse. By unstopping our ears, I propose, we stand not only to deepen our understanding of an enigmatic artist, but also to expand the horizons of theater scholarship, cross discursive boundaries, and holistically engage multimedial forms of expression in theater, opera, and art.

Abstract:

Thesis: Ph. D., Massachusetts Institute of Technology, Department of Aeronautics and Astronautics, 2015.
Cataloged from PDF version of thesis.
Includes bibliographical references (pages 135-146).
Virtually all robotic and autonomous systems rely on navigation and mapping algorithms (e.g. the Kalman filter or simultaneous localization and mapping (SLAM)) to determine their location in the world. Unfortunately, these algorithms are not robust to outliers and even a single faulty measurement can cause a catastrophic failure of the navigation system. This thesis proposes several novel robust navigation and SLAM algorithms that produce accurate results when outliers and faulty measurements occur. The new algorithms address the robustness problem by augmenting the standard models used by filtering and SLAM algorithms with additional latent variables that can be used to infer when outliers have occurred. Solving the augmented problems leads to algorithms that are naturally robust to outliers and are nearly as efficient as their non-robust counterparts. The first major contribution of this thesis is a novel robust filtering algorithm that can compensate for both measurement outliers and state prediction errors using a set of sparse latent variables that can be inferred using an efficient convex optimization. Next the thesis proposes a batch robust SLAM algorithm that uses the Expectation- Maximization algorithm to infer both the navigation solution and the measurement information matrices. Inferring the information matrices allows the algorithm to reduce the impact of outliers on the SLAM solution while the Expectation-Maximization procedure produces computationally efficient calculations of the information matrix estimates. While several SLAM algorithms have been proposed that are robust to loop closure errors, to date no SLAM algorithms have been developed that are robust to landmark errors. The final contribution of this thesis is the first SLAM algorithm that is robust to both loop closure and landmark errors (incremental SLAM with consistency checking (ISCC)). ISCC adds integer variables to the SLAM optimization that indicate whether each measurement should be included in the SLAM solution. ISCC then uses an incremental greedy strategy to efficiently determine which measurements should be used to compute the SLAM solution. Evaluation on standard benchmark datasets as well as visual SLAM experiments demonstrate that ISCC is robust to a large number of loop closure and landmark outliers and that it can provide significantly more accurate solutions than state-of-the-art robust SLAM algorithms when landmark errors occur.

Abstract:

A naive approach to filtering for feedback control of dynamic systems that is robust and stable is proposed. Simulations are run on the filters presented to investigate the robustness properties of each filter. Each simulation with the comparison of the filters is carried out using the usual mean squared error. The filters to be included are the classic Kalman filter, Krein space Kalman, two adjustments to the Krein filter with input modeling and a second uncertainty parameter, a newly developed filter called the Naive filter, bias corrected Naive, exponentially weighted moving average (EWMA) Naive, and bias corrected EWMA Naive filter.

Abstract:

The main objective of this thesis is to apply ideas and techniques from modern control theory, especially from robust state estimation and model validation, to various important problems in computer vision. Robust model validation is used in texture recognition where new approaches for classifying texture samples and segmenting textured images are developed. Also, a new model validation approach to motion primitive recognition is demonstrated by considering the motion segmentation problem for a mobile wheeled robot. A new approach to image inpainting based on robust state estimation is proposed where the implementation presented here concerns with recovering corrupted frames in video sequences. Another application addressed in this thesis based on robust state estimation is video-based tracking. A new tracking system is proposed to follow connected regions in video frames representing the objects in consideration. The system accommodates tracking multiple objects and is designed to be robust towards occlusions. To demonstrate the performance of the proposed solutions, examples are provided where the developed methods are applied to various gray-scale images, colored images, gray-scale videos and colored videos. In addition, a new algorithm is introduced for motion estimation via inverse polynomial interpolation. Motion estimation plays a primary role within the video-based tracking system proposed in this thesis. The proposed motion estimation algorithm is also applied to medical image sequences. Motion estimation results presented in this thesis include pairs of images from a echocardiography video and a robot-assisted surgery video.

Abstract:

This study traces the career of Robert Francis Kelley and his influence on American-Russian Relations during the nonrecognition period (1917-1933). The focus of this examination is Kelley's role in formulating, implementing, and sustaining America's anti-communist policy developed and solidified during the 1920s and 1930s. Particular attention is given to the senate recognition hearing of 1924, Kelley's training of future diplomats (George Kennan, Charles Bohlen, et al.), and his contributions to the preparations leading to the United States' recognition of Russia in 1933. Using Kelley's papers and personal correspondence, this study shows the growth of a man and the evolution of a policy.

Abstract:

In this project we aim to apply Robust Reinforce-ment Learning algorithms, presented by Doya and Morimoto [1],[2], to control problems. Specifically, we train an agent to balancea pendulum in the unstable equilibrium, which is the invertedstate.We investigate the performance of controllers based on twodifferent function approximators. One is quadratic, and the othermakes use of a Radial Basis Function neural network. To achieverobustness we will make use of an approach similar toH∞control, which amounts to introducing an adversary in the controlsystem.By changing the mass of the pendulum after training, we aimedto show as in [2] that the supposedly robust controllers couldhandle this disruption better than its non-robust counterparts.This was not the case. We also added a random disturber signalafter training and performed similar tests, but we were againunable to show robustness.
I detta projekt applicerar vi Robust Rein- forcement Learning (RRL) algoritmer, framtagna av Doya och Morimoto [1], [2], på reglerproblem. Målet var att träna en agent att balansera en pendel i det instabila jämviktsläget; det inverterade tillståndet. Vi undersökte prestandan hos regulatorer baserade på två value function approximators. Den ena är kvadratisk och den andra en Radial Basis Function neuralt nätverk. För att skapa robusthet så använder vi en metod som är ekvivalent med H∞ - reglering, som innebär att man introducerar en motståndare i reglersystemet. Genom att ändra pendelns massa efter träning, hoppas vi att som i [2] kunna visa att den förment robusta regulatorn klarar av denna störning bättre än sin icke-robusta mostvarighet. Detta var inte fallet. Vi lade även till en slumpmässig störsignal efter träning och utförde liknande tester, men lyckades inte visa robusthet i detta fall heller.

Abstract:

The promised future filled with robots sensing and acting intelligently in the world is near fruition, thanks in part to continuous progress in robotic perception and state estimation. However, a number of challenges remain before state estimation systems and the robots that rely on them can be considered truly reliable. In particular, we must consider what happens when highly complex hardware and software systems designed and validated in laboratory environments enter the unbounded variety of reality. Will these systems fail innocuously or catastrophically? If so, how can we avoid or eliminate these failures to achieve reliable, robust behavior? The premise of this thesis is that engineering constraints and human finitude result in fallible systems that cannot compensate for all possible factors and situations. We refer to the collection of uncompensated factors as the con- text of a system, and propose that variations in context can explain why it is difficult to make state estimation reliable at scale. Vexingly, since context is, by nature, unknowable and unmodeled, we cannot rely on prediction and foresight to compensate for it. Instead, this thesis proposes that state estimation systems can adapt their behavior after deployment to the operating site to correct for unknown contextual effects. An example of this is the widespread and common practice of \parameter tuning", typically performed by a human expert to specialize a system to each deployment. To generalize this and other mechanisms of adaptation, we first develop a general theory of context in estimation and establish a statistical definition for estimation performance. We then develop a practical method for evaluating performance on-site without supervision, enabling estimation systems to observe the effects of context during operation. Finally, we explore automatic parameter tuning and experience-driven failure prediction as two methods of general adaptation. We demonstrate and validate this work on state estimation systems using online data from an instrumented automobile as well as online an indoor ground robot.

Full text

Abstract:

Communication, in its most basic sense, is foundational for any personal, human interaction and relationship. As theatre artists, we are charged with communicating complex story lines, conceptual ideas, and emotion to an audience. Sound communication is paramount to every aspect of a musical production, be it communication between actors/characters, actor and director, amongst the production team, and arguable the most important, between the actors and the audience. My years of education as a Masters in Fine Arts candidate in Musical Theatre have been spent polishing my ability to communicate physical and emotional choices with greater accuracy, depth, and truth. By staging Jason Robert Brown's musical The Last Five Years and performing the role of Jamie, this performance thesis will explore, develop, and examine my mastery of the aforementioned varied forms of communication, all of which are necessary in building a successful musical production. Research will be conducted to gather information on relevant topics, including the history of The Last Five Years, the life of Jason Robert Brown, and his musical and theatrical influences. By further understanding Brown, his life, and his ideas about his works, I hope to more fully understand and communicate the message of the musical itself. A dramatic and musical structural analysis will provide further depth and insight into the piece, with the hopes of informing my production and individual performance. A thorough character analysis will provide connective tissue that will allow myself, as the actor, to more effectively communicate the psychological and emotional make up of the character Jamie. Lastly, the thesis document will culminate with a production journal, documenting the pre-production, rehearsal, and performance process. Through the journaling process, I will document and address the journey that I have experienced with the production, giving focus and attention to its many obstacles and discoveries, successes and failures, all of which have contributed to my personal growth as a young theatre artist.

Abstract:

Le domaine de recherche de cette thèse est l'optimisation linéaire robuste en deux étapes. Nous sommes intéressés par des algorithmes d'exploration de sa structure et aussi pour ajouter des alternatives afin d'atténuer le conservatisme inhérent à une solution robuste. Nous développons des algorithmes qui incorporent ces alternatives et sont personnalisés pour fonctionner avec des exemples de problèmes à moyenne ou grande échelle. En faisant cela, nous expérimentons une approche holistique du conservatisme en optimisation linéaire robuste et nous rassemblons les dernières avancées dans des domaines tels que l'optimisation robuste basée sur les données, optimisation robuste par distribution et optimisation robuste adaptative. Nous appliquons ces algorithmes dans des applications définies du problème de conception / chargement du réseau, problème de planification, problème combinatoire min-max-min et problème d'affectation de la flotte aérienne. Nous montrons comment les algorithmes développés améliorent les performances par rapport aux implémentations précédentes
The research scope of this thesis is two-stage robust linear optimization. We are interested in investigating algorithms that can explore its structure and also on adding alternatives to mitigate conservatism inherent to a robust solution. We develop algorithms that incorporate these alternatives and are customized to work with rather medium or large scale instances of problems. By doing this we experiment a holistic approach to conservatism in robust linear optimization and bring together the most recent advances in areas such as data-driven robust optimization, distributionally robust optimization and adaptive robust optimization. We apply these algorithms in defined applications of the network design/loading problem, the scheduling problem, a min-max-min combinatorial problem and the airline fleet assignment problem. We show how the algorithms developed improve performance when compared to previous implementations

Abstract:

Telecommunication networks become major parts in modern complex control systems recently. They provide many advantages over conventional point-to-point connections, such as the simplification on installation and maintenance with comparatively low cost and the nature requirement of wireless communication in remote control systems. In practice, limited resource networks are shared by multiple controllers, sensors and actuators, and they may need to serve some other information unrelated to control purpose. Consequently, the control system design in networked control systems should be revised by taking communication constraints, for example, finite precision data, time delay and noise in transmission, into account. This thesis studies the robust control and state estimation of uncertain systems, when feedback information is sent via limited capacity communication channels. It focuses on the problem of finite precision data due to the communication constraints. The proposed schemes are based on the robust set-valued state estimation and the optimal control techniques. A state estimation problem of linear uncertain system is studied first. In this problem, we propose an algorithm called coder-decoder for uncertain systems. The coder encodes the observed output into a finite-length codeword and sends it to the decoder that generates the estimated state based on the received codeword. As an illustration, we apply the results in state estimation problem to a precision missile guidance problem using sensor fusion. In this problem, the information obtained from remote sensors is transmitted through limited capacity communication networks to the guided missile. Next, we study a stabilization problem of linear uncertain systems with state feedback. In this problem, the coder-controller scheme is developed to asymptotically stabilize the uncertain systems via limited capacity communication channels. The coder encodes the full state variable into a finite-length codeword and sends it to the controller that drives the system state to the origin. To achieve the asymptotic stability, we use a dynamic quantizer so that quantization noise converges to zero. The results in both state estimation and stabilization problems can handle the problem of finite data rate communication networks in control systems.

Abstract:

This thesis proposes the use of a probabilistic state-space model with mixed-linear dynamics for learning to predict a robot's experiences. It is motivated by a desire to bridge the gap between traditional models with predefined objective semantics on the one hand, and the biologically-inspired "black box" behavioural paradigm on the other. A novel EM-type algorithm for the model is presented, which is less compuationally demanding than the Monte Carlo techniques developed for use in (for example) visual applications. The algorithm's E-step is slightly approximative, but an extension is described which would in principle make it asymptotically correct. Investigation using synthetically sampled data shows that the uncorrected E-step can any case make correct inferences about quite complicated systems. Results collected from two simulated mobile robot environments support the claim that mixed-linear models can capture both discontinuous and continuous structure in world in an intuitively natural manner; while they proved to perform only slightly better than simpler autoregressive hidden Markov models on these simple tasks, it is possible to claim tentatively that they might scale more effectively to environments in which trends over time played a larger role. Bayesian confidence regions—easily by mixed-linear model— proved be an effective guard for preventing it from making over-confident predictions outside its area of competence. A section on future extensions discusses how the model's easy invertibility could be harnessed to the ultimate aim of choosing actions, from a continuous space of possibilities, which maximise the robot's expected payoff over several steps into the future

Abstract:

State machine replication (SMR) is a software technique for tolerating failures using commodity hardware. The critical service to be made fault-tolerant is modeled by a state machine. Several, possibly different, copies of the state machine are then deployed on different nodes. Clients of the service access the replicas through a SMR protocol which ensures that, despite concurrency and failures, replicas perform client requests in the same order. Two objectives underly the design and implementation of a SMR protocol: robustness and performance. Robustness conveys the ability to ensure availability (liveness) and one-copy semantics (safety) despite failures and asynchrony. On the other hand, performance measures the time it takes to respond to a request (latency) and the number of requests that can be processed per time unit (throughput). In this thesis, we present two contributions to state machine replication. The first contri- bution is LCR, a uniform total order broadcast (UTO-broadcast) protocol that is throughput optimal in failure-free periods. LCR can be used to totally order the requests received by a replicated state machine. LCR has been designed for small clusters of homogeneous machines interconnected by a local area network. It relies on a perfect failure detector and tolerates the crash failures of all but one replicas. It is based on a ring topology and only relies on point-to-point inter-process communication. We benchmark an implementation of LCR against two of the most widely used group communication packages and show that LCR provides higher throughput than them, over a large number of setups. The second contribution is Abstract, a new abstraction to simplify the design, proof and implementation of SMR protocols. Abstract focuses on the most robust class of SMR protocols, i.e. those tolerating arbitrary (client and replica) failures. Such protocols are called Byzantine Fault Tolerant (BFT) protocols. We treat a BFT protocol as a composition of instances of our abstraction. Each instance is developed and analyzed independently. To illustrate our approach, we first show how, with our abstraction, the benefits of a BFT protocol like Zyzzyva could have been developed using less than 24% of the actual code of Zyzzyva. We then present Aliph, a new BFT protocol that outperforms previous BFT protocols both in terms of latency (by up to 30%) and throughput (by up to 360%).

Abstract:

In this thesis, a novel robust estimation strategy for observing the system state variables of robotic manipulators with distributed flexibility is established. Motivation for the derived approach stems from the observation that lightweight, high speed, and large workspace robotic manipulators often suffer performance degradation because of inherent structural compliance. This flexibility often results in persistent residual vibration, which must be damped before useful work can resume. Inherent flexibility in robotic manipulators, then, increases cycle times and shortens the operational lives of the robots. Traditional compensation techniques, those which are commonly used for the control of rigid manipulators, can only approach a fraction of the open-loop system bandwidth without inducing significant excitation of the resonant dynamics. To improve the performance of these systems, the structural flexibility cannot simply be ignored, as it is when the links are significantly stiff and approximate rigid bodies. One thus needs a model to design a suitable compensator for the vibration, but any model developed to correct this problem will contain parametric error. And in the case of very lightly damped systems, like flexible robotic manipulators, this error can lead to instability of the control system for even small errors in system parameters. This work presents a systematic solution for the problem of robust state estimation for flexible manipulators in the presence of parametric modeling error. The solution includes: 1) a modeling strategy, 2) sensor selection and placement, and 3) a novel, multiple model estimator. Modeling of the FLASHMan flexible gantry manipulator is accomplished using a developed hybrid transfer matrix / assumed modes method (TMM/AMM) approach to determine an accurate low-order state space representation of the system dynamics. This model is utilized in a genetic algorithm optimization in determining the placement of MEMs accelerometers for robust estimation and observability of the system’s flexible state variables. The initial estimation method applied to the task of determining robust state estimates under conditions of parametric modeling error was of a sliding mode observer type. Evaluation of the method through analysis, simulations and experiments showed that the state estimates produced were inadequate. This led to the development of a novel, multiple model adaptive estimator. This estimator utilizes a bank of similarly designed sub-estimators and a selection algorithm to choose the true value from a given set of possible system parameter values as well as the correct state vector estimate. Simulation and experimental results are presented which demonstrate the applicability and effectiveness of the derived method for the task of state variable estimation for flexible robotic manipulators.

Abstract:

As compared to short-term forecasting (e.g., 1 day), it is often challenging to accurately forecast the volume of precipitation in a medium-term horizon (e.g., 1 week). As a result, fluctuations in water inflow can trigger generation shortage and electricity price spikes in a power system with major or predominant hydro resources. In this paper, we study a two-stage robust scheduling approach for a hydrothermal power system. We consider water inflow uncertainty and employ a vector autoregressive (VAR) model to represent its seasonality and accordingly construct an uncertainty set in the robust optimization approach. We design a Benders' decomposition algorithm to solve this problem. Results are presented for the proposed approach on a real-world case study.

Abstract:

Following a paper published by E. Boje[1], this thesis discusses the design and off-line testing of different types of Kalman filters to estimate the attitude, position and velocity of a robotic platform moving along a power line. The nature of this problem limits the use of magnetometers. Magnetic field interference from the steel pylons and steel cored conductors will affect the local magnetic field. Moreover, high frequency signals from on-board power electronic drives and induced magnetic fields due to ferromagnetic components of the robot along with aliasing, quantization effects and a low signal to noise ratio make notch filtering at 50 Hz impractical. Thus, a GPS/IMU filter solution, which uses the power line curvature and horizontal direction in measurements, to constrain the robot to the line was designed. Different types of filters were implemented; The Extended Kalman filter (EKF), the Unscented Kalman filter (UKF) and the Error State Kalman filter (ErKF). Measurements were recorded and the filters were tested offline. While all the filters tracked properly, it was found that the EKF was better in computational speed completing an iteration in 87 µs, the ErKF was second best with an average time of 120 µs for one iteration and the UKF was last with an average time of 1040 µs for one iteration. Errors between the true state and estimated state for the simulation were quantified using root mean square values (RMS). The RMS values were almost the same for the EKF and ErKF with the error for the x position at 0.81 m and z position at 0.038 m. The UKF produced RMS errors of 0.79 m for x position and 0.11 m for z position. It can be seen that the UKF is slightly better for the x position but is much worse for the z position. Overall, the GPS measurement RMS values used were 4 m and 20 m for the horizontal and vertical positions respectively. Thus, the filters brought a big improvement. However, the recommended filter is the EKF as is produced comparable or better results as compared to other filters and expends the least computational effort. A state estimator was also developed for a J.Patel’s PLIR project [2], where a brachiating version of a power line robot was modeled. The brachiation mechanism was approximated to a double pendulum and kinematics based Kalman filter was designed. Simulations of EKF and UKF were made. The EKF is still recommended as its estimates are closer to the true values and its computation time is about five times faster.

Abstract:

The work presented in this thesis was motivated by the desire to establish an alternative approach to the design of robust polynomial controllers. The procedure of pole-placement forms the basis of the design and for polynomial systems this generally involves the solution of a diophantine equation. This equation has many possible solutions which leads directly to the idea of determining the most appropriate solution for improved performance robustness. A thorough review of many of the aspects of the diophantine equation is presented, which helps to gain an understanding of this extremely important equation. A basic investigation into selecting a more robust solution is carried out but it is shown that, in the polynomial framework, it is difficult to relate decisions in the design procedure to the effect on performance robustness. This leads to the approach of using a state space based design and transforming the resulting output feedback controller to polynomial form. The state space design is centred around parametric output feedback which explicitly represents a set of possible feedback controllers in terms of arbitrary free parameters. The aim is then to select these free parameters such that the closed-loop system has improved performance robustness. Two parametric methods are considered and compared, one being well established and the other a recently proposed scheme. Although the well established method performs slightly better for general systems it is shown to fail when applied to this type of problem. For performance robustness, the shape of the transient response in the presence of model uncertainty is of interest. It is well known that the eigenvalues and eigenvectors play an important role in determining the transient behaviour and as such the sensitivities of these factors to model uncertainty forms the basis on which the free parameters are selected. Numerical optimisation is used to select the free parameters such that the sensitivities are at a minimum. It is shown both in a simple example and in a more realistic application that a significant improvement in the transient behaviour in the presence of model uncertainty can be achieved using the proposed design procedure.

In this thesis, we propose strategies to solve the general ground state problem for arbitrary effective cluster interactions and construct ground state preserving cluster expansions. A full mathematical definition of our problem has been formalized to illustrate its generality and clarify our discussion. We review previous methods in material science community: Monte Carlo based method, configurational polytope method, and basic ray method. Further, we investigate the connection of the ground state problem with deeper mathematical results about computational complexity and NP-hard combinatorial optimization (MAX-SAT). We have proposed a general scheme, upper bound and lower bound calculation to approach this problem. Firstly, based on the traditional configurational polytope method, we have proposed a method called cluster tree optimization method, which eliminates the necessity of introducing an exponential number of variables to counter frustration, and thus significantly improves tractability. Secondly, based on convex optimization and finite optimization without periodicity, we have introduced a beautiful MAX-MIN method to refine lower bound calculation. Finally, we present a systematic and mathematically sound method to obtain cluster expansion models that are guaranteed to preserve the ground states of the reference data.

Full text

Abstract:

In this thesis we consider the development of a general nonlinear input-output theory which encompasses systems with initial conditions. Appropriate signal spaces (i.e., interval spaces, extended spaces and ambient spaces) are introduced with some fundamental assumptions to constitute a framework for the study of input-output systems with abstract initial conditions. Both systems and closed-loop systems are defined in a set theoretic manner from input-output pairs on a doubly infinite time axis, and a general construction of the initial conditions (i.e., a state at time zero) is given in terms of an equivalence class of trajectories on the negative time axis. Fundamental properties (such as existence, uniqueness, well-posedness and causality) of both systems and closed-loop systems are defined and discussed from a very natural point of view. Input-output operators are then defined for given initial conditions, and a suitable notion of input-output stability on the positive time axis with initial conditions is given. This notion of stability is closely related to the ISS/IOS concepts of Sontag. A fundamental robust stability theorem is derived which represents a generalisation of the input-output operator robust stability theorem of Georgiou and Smith to include the case of initial conditions; and can also be viewed as a generalisation of the ISS approach to enable a realistic treatment of robust stability in the context of perturbations which fundamentally change the structure of the state space. This includes a suitable generalisation of the nonlinear gap metric. Generalisations of this robust stability result are also extended to finite-time reachable systems and to systems with potential for finite-time escape by extending signals on extended spaces to a wider space (ambient space). Some linear and nonlinear applications are given to show the effects of the robust stability results. We also present a generalised nonlinear ISS-type small-gain result in this input-output structure set up in this thesis, which is established without extra observability conditions and with complete disconnection between the stability property and the existence, uniqueness properties of systems. Connections between Georgiou and Smith's robust stability type theorems and the nonlinear small-gain theorems are also discussed. An equivalence between a small-gain theorem and a slight variation on the fundamental robust stability result of Georgiou and Smith is shown.
