Full text

Abstract:

The pole assignment problem has been subject for research for a long time. For single-input single-output systems this problem is well understood but for multi-input multi-output systems the pole assignment problem is more complex. In this thesis a parameterization of state feedback gains for pole assignment is characterized with respect to completeness, redundancy and existence. In order to make a systematic examination of this parameterization a number of classes are introduced. This parameterization depends on two matrices that can be regarded as design parameters. In the thesis it is shown how the degree of freedom in the pole assignment problem for multi-input systems is characterized by these two matrices. It turns out that the properties of the parameterization depends on whether the characteristic polynomials of the open and the closed loop systems are coprime or not. It is shown in the thesis that if the characteristic polynomials are coprime, every possible feedback gain can be parameterized in this way, and in this sense the parameterization is complete. If the characteristic polynomials have factors in common the parameterization is not complete. In the thesis the shortcomings of the parameterization for this case are characterized. The design parameters seem to offer a greater degree of freedom than what can be offered in the pole assignment problem. This indicates a certain degree of overparameterization. This redundancy in the design parameters is characterized in the thesis. The parameterization implies that a certain matrix is invertible. Necessary conditions for when this matrix is invertible are given in terms of the two design parameters. It is shown that this matrix is invertible for almost every value of the design parameters when the characteristic polynomials are coprime, and hence that the parameterized gains are generally applicable. The parameterization and its properties are illustrated on a linear model of the military aircraft JAS Gripen.

Full text

Abstract:

This thesis presents decentralized model reference adaptive control techniques for systems with full-state feedback and systems with output feedback. The controllers are strictly decentralized, that is, each local controller uses feedback from only local subsystems and no information is shared between local controllers. The full-state feedback decentralized controller is effective for multi-input systems, where the dynamics matrix and control-input matrix are unknown. The decentralized controller achieves asymptotic stabilization and command following in the presence of sinusoidal disturbances with known spectrum. We present a construction technique of the reference-model dynamics such that the decentralized controller is effective for systems with arbitrarily large subsystem interconnections. The output-feedback decentralized controller is effective for single-input single-output subsystems that are minimum phase and relative degree one. The decentralized controller achieves asymptotic stabilization and disturbance rejection in the presence of an unknown disturbance, which is generated by an unknown Lyapunov-stable linear system.

Abstract:

This thesis concerns the development of robust nonlinear control design for complex systems including nonholonomic systems and large-scale systems using sliding mode control (SMC) techniques under the assumption that all system state variables are accessible for design. The main developments in this thesis include: 1). The concept of generalised regular form and design of a novel sliding function. The mathematical definition of generalised regular form is proposed for the first time. It is an extension of the classical regular form, which makes SMC applicable to a wider class of nonlinear systems. A novel sliding function design, which is based on the global implicit function theorem, is proposed to guarantee unique sliding mode dynamics. 2). The development of decentralised SMC for large-scale interconnected systems. For systems with uncertain interconnections which possess the superposition property, a decentralised control scheme is presented to counteract the effect of the uncertainty by using bounds on uncertainties and interconnections. The bounds used in the design are nonlinear functions instead of constant, linear or polynomial functions. The design strategy has also been expanded to a fully nonlinear case for interconnected systems in the generalised regular form. 3). Robust decentralised SMC for a class of nonlinear systems with uncertainties in input distribution. A system with uncertainties in input distribution is full of challenges. A novel method is proposed to deal with such uncertainties for a class of nonlinear interconnected systems. The designed decentralised SMC enhances the robustness of the controlled systems. This thesis also provides case studies of three applications for the proposed approaches. The existence of the generalised regular form is verified in the trajectory tracking control of a wheeled mobile robot (WMR) system. Both simulations and experiments on the WMR are given to demonstrate the validity and effectiveness of the generalised regular form-based SMC design. A continuous stirred tank reactor (CSTR) system and a longitudinal vehicle-following system are used to test the proposed decentralised SMC schemes. An expanded vehicle-following system with both longitudinal and lateral controllers has been developed to demonstrate the robust control design for system with uncertainties in input distribution.

Abstract:

Asymptotic stability is a key notion of system stability for controlled dynamical systems as it guarantees that the system trajectories are bounded in a neighborhood of a given isolated equilibrium point and converge to this equilibrium over the infinite horizon. In some applications, however, asymptotic stability is not the appropriate notion of stability. For example, for systems with a continuum of equilibria, every neighborhood of an equilibrium contains another equilibrium and a nonisolated equilibrium cannot be asymptotically stable. Alternatively, in stabilization of spacecraft dynamics via gimballed gyroscopes, it is desirable to find state- and output-feedback control laws that guarantee partial-state stability of the closed-loop system, that is, stability with respect to part of the system state. Furthermore, we may additionally require finite-time stability of the closed-loop system, that is, convergence of the system's trajectories to a Lyapunov stable equilibrium in finite time. The Hamilton-Jacobi-Bellman optimal control framework provides necessary and sufficient conditions for the existence of state-feedback controllers that minimize a given performance measure and guarantee asymptotic stability of the closed-loop system. In this research, we provide extensions of the Hamilton-Jacobi-Bellman optimal control theory to develop state-feedback control laws that minimize nonlinear-nonquadratic performance criteria and guarantee semistability, partial-state stability, finite-time stability, and finite-time partial state stability of the closed-loop system.

Abstract:

Abstract Electrorheological (ER) fluids have electrically controllable stiffness, viscosity, and heat transfer properties. Since the 1940s researchers have attempted to model the properties of ER fluids and have proposed applications which attempt to utilize their special characteristics in the operation of hydraulic valves, soft clutches, and active suspension systems. Early attempts to make these applications commercially successful were hampered by the relatively slow, nonlinear response of ER fluids under on-off control of high electric fields. Successful applications will require fast, precise control of the response of ER fluids, independent of application at low field strengths. This study presents a new approach to the control of ER fluids that overcomes the problems of imprecise, slow, nonlinear response and high electric fields. An optical sensor was used to indicate the ER fluid state in a layered composite window. Feedback control of ER fluid state was developed and compared to conventionally actuated ER fluids. Feedback control employs the state sensor and high initial electric field strength to speed ER state response, then lowers the field strength to the minimum level required to achieve the desired ER fluid state. Predicted responses were compared to experimentally measured responses and showed excellent agreement. Laboratory measurements showed a proportional state feedback control system yielded an electrorheological fluid that responded 35 times faster and 21 times more accurately than possible with a conventional open-loop fluid control system. Although the use of ER fluids in feedback control systems have been proposed in the past, this work is the first application of feedback control to the fluid itself.

Abstract:

High exhaust emissions reduction efficiencies from a spark ignited (SI) internal combustion engine utilizing an NSCR catalyst system requires complex fuel control strategies. The allowable equivalence ratio operating range is very narrow where NSCR systems achieve high exhaust emissions reduction efficiencies of multiple species. Current fuel control technologies utilizing lambda sensor feedback are reported to be unable to sustain these demands for extended operation periods and when transients are introduced. Lambda sensor accuracy is the critical issue with current fuel controllers. The goal of this project was to develop a minimization control algorithm utilizing a Nitrogen Oxide (NOx) sensor installed downstream of the NSCR catalyst system for feedback air/fuel ratio control. When the engine is operated lean, NOx is produced and the NOx sensor responds accordingly. When the engine is operated rich, the NSCR catalyst system produces Ammonia. The NOx sensor has a cross sensitivity to Ammonia and responds as though it has been exposed to NOx. This behavior provides an opportunity for a unique control strategy that allows lambda sensor calibration to be ignored. Testing was performed on a 100kW rated Cummins-Onan generator set that was reconfigured to operate utilizing an electronic gas carburetor (EGC2) with lambda sensor feedback and high reduction efficiency NSCR catalyst system. The control algorithm was programmed utilizing a Labview interface that communicated with the electronic gas carburetor where the fuel trim adjustment was physically made. Improvement under steady state operation was observed. The system was also evaluated during load and fuel composition transients.

Abstract:

�The purpose of this project was to evaluate the performance of electronic fuel gas admission valves and effects of continuous automatic cylinder balancing of large bore natural gas engines under actual field conditions. These goals have already been met under laboratory conditions at the Colorado State University Engines and Energy Conversion Laboratory in Fort Collins. The specific project objectives were to:1. Extend the feasibility of electronic fuel gas admission valves where gas valve timing and duration are varied to optimize fuel control and charge mixing from the laboratory environment to actual field applications. 2. Extend the feasibility of closed loop control using in-cylinder pressure sensors to achieve continuous, automatic power cylinder balancing from the laboratory environment to actual field applications. 3. Repeat the benefits of automatic continuous cylinder balancing shown in the laboratory testing under actual field conditions (i.e. fuel savings, improved cylinder misfire rates, improved emissions levels). In order to accomplish these objectives, the Woodward Governor Company AutoBalance TM 5000 control system was installed and tested at four host sites. Although the specific test plan differed slightly for the four host sites, the focus of the test program was consistent. The primary objective was to evaluate the effects of engine balance and the performance of the control system by testing a matrix of varying engine loads and speeds. Load and speed are the two primary control parameters affecting engine balance. Other tests were conducted to determine the effects of the electronic gas admission valve (EGAV) configuration (i.e. start of admission, end of admission, and duration).

Abstract:

In 2014, reports suggested that a surge of foreign jihadists were participating in armed conflicts in Syria, Iraq, and elsewhere. The United Nations Security Council responded by imposing in Resolution 2178 (2014) an array of obligations on member states to counter the threat posed by “foreign terrorist fighters” (FTFs). In the intervening year, those states have taken a range of actions — though at various speeds and with varying levels of commitment — to implement the FTF obligations imposed by the Council. Meanwhile, many states continue to fund and otherwise throw their support behind life-saving humanitarian relief for civilians in armed conflicts around the world — including conflicts involving terrorists. Yet, in recent years, members of the humanitarian community have been increasingly aware of the real, perceived, and potential impacts of counterterrorism laws on humanitarian action. Part of their interest stems from the fact that certain counterterrorism laws may, intentionally or unintentionally, adversely affect principled humanitarian action, especially in regions where terrorist groups control territory (and thus access to civilians, too). The effects of these laws may be widespread — ranging from heightened due diligence requirements on humanitarian organizations to restrictions on travel, from greater government scrutiny of national and regional staff of humanitarian organizations to decreased access to financial services and funding. Against that backdrop, this briefing report has two aims: first, to provide a primer on the most salient issues at the intersection of counterterrorism measures and humanitarian aid and assistance, with a focus on the ascendant FTF framing. And second, to put forward, for critical feedback and assessment, a provisional methodology for evaluating the following question: is it feasible to subject two key contemporary wartime concerns — the fight against FTFs and supporting humanitarian aid and assistance for civilians in terrorist-controlled territories — to meaningful empirical analysis?

Abstract:

The pipeline industry uses over 8,000 large bore engines in gas transmission/compression service". These engines are typically gas fueled and spark ignited. Some early versions of the engines are piston scavenged, but most are turbocharged. Some models, especially those equipped for lean burn operation, utilize pre-combustion chambers for enhanced ignition. Typically, the gaseous fuel is admitted directly into the top of the engine combustion chamber by a cam-operated, mechanical gas admission valve (MGAV). The MGAV is operated by an engine driven cam, cam follower, push rod, and rocker assembly. Such mechanisms offer little in the way of adjustability of the gas admission event: the ability to change the start of gas admission (SOA) and end of gas admission (EOA). The gas admission system is generally optimized for a particular mode of engine operation, typically rated speed and full load, and is fixed in that state. Desired changes in the gas admission cycle are not easily accomplished. At the same time, however, undesired changes commonly occur due to wear, failure, and mis-adjustment of the MGAV drive train. This report documents the development of a natural gas-fueled large-bore engine test bed (LBET) at Colorado State University and the subsequent test of an electronic gas admissions valve (EGAV) with in-cylinder pressure feedback. The LBET is now a state-of-the-art natural gas-fueled test facility. It will be open for use in late 1994 or early 1995 to all parties interested in testing equipment that might lead to safer, more economical and cleaner burning gas fueled engines. The EGAV tests were successful. The valve allows for precise control of fuel admission and end of admission timing. This results in the engine running in a real-time balance condition. Laboratory tests showed a 30% reduction of hydrocarbons and nitrous oxides reductions with a 2% reduction in fuel consumption. Field testing will continue in 1995 prior to commercialization.

Abstract:

Work zone safety is a high priority for transportation agencies across the United States. High speeds in construction zones are a well-documented risk factor that increases the frequency and severity of crashes. It is therefore important to understand the extent and severity of high-speed vehicles in and around construction work zones. This study uses CV trajectory data to evaluate the impact of several work zone speed compliance measures, such as posted speed limit signs, radar-based speed feedback displays, and automated speed enforcement on controlling speeds inside the work zone. This study also presents several methodologies to characterize both the spatial and temporal effects of these control measures on driver behavior and vehicle speeds across the work zones.
