Texto completoSuccessful multivariable control system design demands knowledge, skill and creativity of the designer. The goal of the research described in this dissertation was to investigate, implement, and evaluate methods by which artificial intelligence techniques, in a broad sense, may be used in a design system to assist the user. An intelligent, interactive, control system design tool has been developed to fulfil this aim. The design tool comprises two main components; an expert system on the upper level, and a powerful CACSD package on the lower level. The expert system has been constructed to assist and guide the designer in using the facilities provided by the underlying CACSD package. Unlike other expert systems, the user is also aided in formulating and refining a comprehensive and achievable design specification, and in dealing with conflicts which may arise within this specification. The assistance is aimed at both novice and experienced designers. The CACSD package includes a synthesis program which attempts to find a controller that satisfies the design specification. The synthesis program is based upon a recent factorization theory approach, where the linear multivariable control system design problem is translated into, and techniques efficiency solved as, a quadratic programming problem, which significantly improve the time and space of this method have been developed, making it practical to solve substantial multivariable design problems using only a microcomputer. The design system has been used by students at the University of Cape Town. Designs produced using the expert system tool are compared against those produced using classical design methods.

Texto completoEn esta tesis, presentamos el desarrollo de un nuevo concepto de operación de telescopio robótica operados a través de Internet. Nuestro diseño incluye un conjunto de mejoras de los algoritmos de control y hardware de varios puntos críticos de la lista de subsistemas necesarios para obtener datos de calidad científica con un telescopio. Podemos sintetizar las principales contribuciones de esta tesis en cinco innovaciones independientes: - Un control de motor avanzado en bucle cerrado: Diseñamos un hardware y software innovadores para controlar la posición y movimiento fino de un telescopio con alta precisión y alta robustez. - Un software de control de telescopio (TCS) integrado: Implementamos un software ligero y portátil que ocupa bibliotecas de algoritmos astronómicos avanzados para calcular de manera óptima y en tiempo real la posición teórica del telescopio. Este software también proporciona un software innovador de modelo de pointing múltiples simultáneos. Esto permite alcanzar una mayor precisión de seguimiento y así ocupar tiempos de integración más importante ocupando un telescopio de guía mecánicamente apartado al telescopio principal. - Una arquitectura de software distribuido (CoolObs): CoolObs es una implementación de software ocupando la plataforma de desarrollo ZeroC-ICE la cual permite el control, la interacción y la comunicación de todos los periféricos presentes en un observatorio astronómico. - Un sistema patentado para la colimación dinámica de la óptica: SAPACAN es un sistema mecánico de movimiento paralelo y su software asociado. Se puede ocupar para compensar activamente las aberraciones ópticas de bajo orden en pequeños telescopios. - Algoritmos de estimación de colimación: Se desarrolló un algoritmo de óptica adaptiva sin sensor en base al análisis de imágenes obtenidas con una cámara cerca del plano focal del telescopio. Este algoritmo puede detectar efectos de mala colimación de las ópticas. Los desajustes, una vez medidos, pueden posteriormente ser aplicados como correcciones a un dispositivo como SAPACAN. Astronomía es un terreno propicio al desarrollo de nuevas tecnologías y, debido a esto, los protocolos de comunicación entre periféricos pueden ser obsoletos porque se han escritos en etapas tempranas de existencia de estas nuevas tecnologías. Las mejoras se han hecho de a poco para mantener la compatibilidad de los sistemas ya existentes, ocupando un planteamiento general de la problemática de control de telescopios robóticos, proponemos un nuevo concepto de observatorio robótico visto como una entidad y no una lista de periféricos independientes. A lo largo de esta tesis, describiremos la aplicación de este concepto en el campo de telescopios robóticos e implementarlo en varios sistemas independientes y variados para mostrar la versatilidad y robustez de la propuesta.

Texto completoThere are many aspects to consider when designing system identification experiments in control applications. Input design is one important issue. This thesis considers input design both for identification of linear time-invariant models and for stability validation.
Models obtained from system identification experiments are uncertain due to noise present in measurements. The input spectrum can be used to shape the model quality. A key tool in input design is to introduce a linear parametrization of the spectrum. With this parametrization a number of optimal input design problems can be formulated as convex optimization programs. An Achilles' heel in input design is that the solution depends on the system itself, and this problem can be handled by iterative procedures where the input design is based on a model of the system. Benefits of optimal input design are quantified for typical industrial applications. The result shows that the experiment time can be substantially shortened and that the input power can be reduced.
Another contribution of the thesis is a procedure where input design is connected to robust control. For a certain system structure with uncertain parameters, it is shown that the existence of a feedback controller that guarantees a given performance specification can be formulated as a convex optimization program. Furthermore, a method for input design for multivariable systems is proposed. The constraint on the model quality is transformed to a linear matrix inequality using a separation of graphs theorem. The result indicates that in order to obtain a model suitable for control design, it is important to increase the power of the input in the low-gain direction of the system relative to the power in the high-gain direction.
A critical issue when validating closed-loop stability is to obtain an accurate estimate of the maximum gain of the system. This problem boils down to finding the input signal that maximizes the gain. Procedures for gain estimation of nonlinear systems are proposed and compared. One approach uses a model of the system to design the optimal input. In other approaches, no model is required, and the system itself determines the optimal input sequence in repeated experiments.

Texto completoDevelopment of modern aircraft has become more and more expensive and time consuming. In order to minimize the development cost, an improvement of the conceptual design phase is needed. The desired goal of the project is to enhance the functionality of an in house produced framework conducted at the department of machine design, consisting of parametric models representing a large variety of aircraft concepts.
The first part of the work consists of the construction of geometric aircraft control surfaces such as flaps, aileron, rudder and elevator parametrically in CATIA V5.
The second part of the work involves designing and simulating an Inverse dynamic model in Dymola software.
An Excel interface has been developed between CATIA and Dymola. Parameters can be varied in the interface as per user specification; these values are sent to CATIA or Dymola and vice versa. The constructed concept model of control surfaces has been tested for different aircraft shapes and layout. The simulation has been done in Dymola for the control surfaces.

Texto completoControllability is the ability of a process to achieve acceptable performance, and in this thesis we use controllability analysis in the design of buffer tanks, feedforward controllers, and multivariable controllers such as model predictive control (MPC).
There is still an increasing pressure on the process industry, both from competitors (prize and quality) and the society (safety and pollution), and one important contribution is a smooth and stable production. Thus, it is important to dampen the effect of uncontrolled variations (disturbances) that the process may experience.
The process itself often dampens high-frequency disturbances, and feedback controllers are installed to handle the low-frequency part of the disturbances, including at steady state if integral action is applied. However, there may be an intermediate frequency range where neither of these two dampens the disturbances sufficiently. In the first part of this thesis we present methods for the design of buffer tanks based on this idea. Both mixing tanks for quality disturbances and surge tanks with “slow” level control for flow-rate variations are addressed.
Neutralization is usually performed in one or several mixing tanks, and we give recommendations for tank sizes and the number of tanks. With local PI or PID control, we recommend equal tanks, and give a simple formula for the total volume. We also give recommendations for design of buffer tanks for other types of processes. We propose first to determine the required transfer function to achieve the required performance, and thereafter to find a physical realization of this transfer function.
Alternatively, if measurements of the disturbances are available, one may apply feedforward control to handle the intermediate frequency range. Feedforward control is based mainly on a model, and we study the effect of model errors on the performance. We define feedforward sensitivities. For some model classes we provide rules for when the feedforward controller is effective, and we also design robust controllers such as μ -optimal feedforward controllers.
Multivariable controllers, such as model predictive control (MPC), may use both feedforward and feedback control, and the differences between these two also manifest themselves in a multivariable controller. We use the class of serial processes to gain insight into how a multivariable controller works. For one specific MPC we develop a state space formulation of the controller and its state estimator under the assumption that no constraints are active. Thus, for example the gains of each channel of the MPC (from measurements to the control inputs) can be found, which gives further insight into to the controller. Both a neutralization process example and an experiment are used to illustrate the ideas.

The exoskeleton was developed to assist the elderly in keeping their walking function, by actuating pneumatic muscles with user’s gait feedback. Thin-film pressure sensors were applied to feedback foot pressures and identify walking gait of the user. A controller interpreted the gait by those input foot pressures and send out corresponding actuating signals to pneumatic muscles. As with aid in getting up from a chair, the system provides also aids in walking on a flat surface, up and down stairs. Thin-film pressure sensors, two for each foot, were buried under heel and metatarsal regions. Experiments confirmed that the foot pressure signals provided could actually inspire the expected actuations of pneumatic muscles and help the walking function. Without attaching sensors to the human body, the proposed scheme is more convenient and comfortable when comparing to the case with a need of sensor attachments. Keyword: exoskeleton control, film-type pressure sensors, gait analysis

This dissertation focuses on the design of the following two intelligent controllers: fuzzy controller and extension controller. For the fuzzy controller, three parameters including control rules, membership functions, and scaling factor are well distinct adapted using adaptation approach. A new rule analytical form with multi-variables is proposed such that the direct and indirect adaptation approaches can be successfully applied to high order systems. A fuzzy sliding mode controller via rule adaptation is also shown in the contents. Such structure of fuzzy controller is usually easier than that of using state variables, because the fuzzy sliding mode controller contains less input variables. Regarding to the membership functions adaptation, only one parameter is used to adapt the membership functions. After adaptation, the membership functions are always equally distributed over the universe of discourse. Here, we focus on the design of direct and indirect fuzzy sliding mode controllers. For the scaling factor adaptation, two popular types, Mamdani and Takagi-Sugeno fuzzy controllers, are investigated. Of course, the best advantage of scaling factor is that the remaining parameters of fuzzy controller including rules and membership functions do not need to change under control, we can determine it under control common sense. Combination of the Mamdani and the Takagi-Sugeno models in designing the indirect fuzzy control via scaling factor adaptation is also studied. Two robust control terms, bang-bang control and hitting control, are illustrated in order to guarantee the stability of developed fuzzy control systems. For the extension controller, based on the scheme of adaptive and sliding mode control, two distinct extension controllers are investigated. Some simulation works of nonlinear control system for the developed controllers are given. As to what we expect, the simulation results show the effectiveness of the developed controllers.

To control various nonlinear systems, the fazzy controller is the most popular metho recently. However, the designs of fuzzy systems depend on knowledge acquisition by experience of domain experts and adjust rule base and membership function by design engineers. The method will spend much time and the performance of the controlled system can not be guaranteed to achieve optimal result. Therefore, we propose direct adaptive fuzzy control system and indirect adaptive fuzzy control system to improve the disadvantages of traditional fuzzy system. Simply speaking, the designed method of direct adaptive fuzzy control system generates a control command from the single fuzzy controller, then feed it back the plant. The designed method of indirect adaptive fuzzy control system is modeling the plant from a number of fuzzy systems at first, then it generates a control command by the dynamic character which will feed it back the plant. Whatever which types of adaptive fuzzy controller, they have the adaptive law of center regulation or rule regulation on line, respectively. The adaptive law not only can overcome the defect of genetic algorithms and simulated annealing which are unable to find the optimal membership function and rule base on line, but also the results of the controlled system will not be influenced, even the plant has many uncertainties, such as the suddenly change of parameters or the external disturbance. Further, we use a few parameter to design the adaptive law in order to reduce the complex of mathematical deduction and increase the speed of computing. Therefore, the fuzzy system becomes more practical and robust.

Antisense oligonucleotides have been widely applied for controlling gene expression at the post-transcriptional level. It may also develop into a new approach for treating various diseases. The control oligonucleotides play an important role in the antisense related experiments. However, there has never been a computer system, which can automatically generate sequences of control oligonucleotides. Researchers usually manually select the control sequences, so the selecting process is always time consuming, labor intensive, and is not very appropriate since it may induces undesirable hybridization or other unexpected effects to the target organisms. The system proposed in this paper generates candidates of control sequences according to users’ input antisense sequences. It employs several formulas for calculating melting temperatures. It also uses several hybridization related criteria to evaluate the candidates and to assist the researchers to select the most suitable control oligonucleotide sequence.

In the program control of the oil tank, the PID is widely used, such as high pressure troughs, atmospheric trenches, etc., and the reason for such popularity is that such controllers are of a generic type and are suitable for a variety of different operating procedures by the mode of the manipulator. At present, there are many PID controllers in the industry. In different environments, the PID parameters are different. In the PID-driven control valve, the widely used temperature control, pressure control. In this paper, we try to use the Ziegler-Nichols rule to calculate the controller parameters by simulating the PID parameters and passing the Ziegler-Nichols rule of thumb. Then use the Ziegler-Nichols rule to calculate the controller parameters to compare with them to find out the most suitable for this experiment In the PID parameter settings. In this paper, the optimal value is K_p=0.8, K_i=0.25, K_d=0.05 by Ziegler-Nichols' rule.Compared with other set values, the operation of the machine is stabilized and the production is improved. effectiveness. Through this study can make the future in the adjustment of PID control, to better understand the needs of customers, not only to ensure the stability of the controller obtained, but also can effectively improve the efficiency of the algorithm, but also make the controller performance More excellent, more robust control performance.

The purpose of predictive theorem is to estimate system model and estimate future system response. On the control system design area, if system variation can be predicted earlier, then future system dynamics can be predict. This will do great benefit to the reliability and control performance of system. The purpose of this paper is to combine system model estimation and predictive control system design, and apply it to shear machine synchronize control, rotated inverted pendulum control and wheel robot balance control. Experimental and simulated results show that the combination of system model estimation and predictive control system can improve controller performance. For example, it can improve rotated inverted pendulum system stability, reduce wheel robot vibration and reduce shear machine overshoot and reduce delay time.

This paper presents that an optimal control system which consists of both feedforward and state-feedback controllers is designed using a well-developed linear quadratic Gaussian and loop transfer recovery (LQG/LTR) method for a fuel processing system (FPS).This FPS uses natural gas as fuel and reacts with atmospheric air through a catalytic partial oxidation (CPO),after pure supply to proton exchange membrane fuel cell (PEMFC) stack . The objectives of this paper are to use the Matlab/Simulink software tool to model such an optimal control system and to analyze the system performance. The proposed method achieves better performance and robustness properties in both time-domain and frequency-domain responses.

Along with the technical development in computer and electronics, home appliances have become smarter and had increasingly more controllable features. Therefore the remote controller for these appliances usually have more buttons; and since many appliances use a remote controller, there will be many more buttons in a house. So, people might need an embedded speech control system to replace the controllers and many buttons. To make the engine Chinese recognizable, a Chinese speech corpus and a Chinese phonetic alphabet are used to train the recognition engine, and we found that the database size increases exponentially with the number of recognizable phones. In addition, we also found that a bottleneck in performance occurs due to the Fast Fourier Transform (FFT) in the feature extraction. Therefore, we analyze the storage capacity and performance of the speech recognition procedure. The most important thing in speeding up the process of the speech recognition is not to affect the accuracy and the recognition rate. In this research, we have found that by using DSP to improve the FFT, we can raise the performance of the feature extraction by tenfold without affecting the accuracy of the system. But on the other way, the recognition is not a compute-intensive operation. It is difficult to speed up by the DSP. So, we propose a practical architecture which has features of unlimit storage capacity, speaker-independence, and fast reaction.
