Available in PDF, EPUB and Kindle. Book excerpt: Procedures for designing piecewise-linear (PWL) switching surfaces for minimum time control are investigated. The approach is to generate the switching function using the instantaneous values of the states as inputs to easily realized PWL function generators. The design problem is then one of fitting the state space PWL surface to points defining the optimal surface. Several performance indices related to minimum-time are defined and the resulting parameter surfaces for different initial condition distributions are studied. However, because of local minima, a successful search procedure could not be found. Therefore, a heuristic method of least squares fitting is used. A combination gradient and generalized Newton-Raphson search method is employed to obtain values for the PWL parameters. Several least squares fit methods are applied to a second order problem and the results compared using response time performance to a uniform grid of initial conditions. Very close to optimal performance is achieved using a delay time design procedure. (Author).
Book Synopsis A Piecewise-Linear Switching Function For Quasi-Minimum-Time Control by : Thomas Stephenson Althouse

This book was released on 1968 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of controllers to provide quasi-minimum time-response is investigated. With the control law to be realized as a piecewise-linear combination of the instantaneous state values, the problem is to select the parameters which define the best suboptimal switching surface. A worst-case response-time performance index is defined and shown to be suitable for use in the suboptimal controller design. A proposed design technique is described and used to determine controllers for second-order systems. The results of the illustrative examples are compared with controllers designed using a least squares polynomial fitting technique. The comparison shows that the proposed method designs significantly better controllers in terms of deviation from optimal response time. (Author).

Book Synopsis Minimum-time Control of a Linear Combination of State Variables by : Charles Edgar Hutchinson
Download or read book Minimum-time Control of a Linear Combination of State Variables written by Charles Edgar Hutchinson and published by . This book was released on 1963 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is concerned with the general problem of minimum-time control of a linear combination of state variables of dynamical systems. The specific problem of interest, which may be cast in the form of the general problem, is that of controlling linear, time-invariant, one-input, one-output systems with zeros of transmission at some (possibly complex) frequencies. The available control effort is magnitude limited, and there are no disturbances. Only the problem of eliminating initial conditions is considered. A detailed analysis of second- and third-order systems is made. The basic mathematical tool used in finding the solution for the general problem is that of Pontryagin's Maximum Principle. Approximate solutions are obtained for both secondand third-order problems in general. The method of approximation utilized is that of a powerseries truncation. These approximations are applicable for a large class of problems with ''small'' errors, where smallness is measureed in terms of the size of the controlling function. (Author).

This book was released on 2011-01-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are plenty of challenging and interesting problems open for investigation in the field of switched systems. Stability issues help to generate many complex nonlinear dynamic behaviors within switched systems. The authors present a thorough investigation of stability effects on three broad classes of switching mechanism: arbitrary switching where stability represents robustness to unpredictable and undesirable perturbation, constrained switching, including random (within a known stochastic distribution), dwell-time (with a known minimum duration for each subsystem) and autonomously-generated (with a pre-assigned mechanism) switching; and designed switching in which a measurable and freely-assigned switching mechanism contributes to stability by acting as a control input. For each of these classes this book propounds: detailed stability analysis and/or design, related robustness and performance issues, connections to other control problems and many motivating and illustrative examples.

This book was released on 2009-10-06 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Papers in this collection partly represent the set of talks that were presented at Texas Tech University on the occasion of Daya’s memorial workshop in the year 2007. Daya had a varied interest in the field of Dynamics and Control Theory and the papers bring out the essence of his involvement in these activities. He also had a large number of collaborators and this collection represent a good fraction of them. The papers included here cover his interest in control theory. Also included are papers from application areas that we believe are of strong interest to him.

Download or read book Pattern Recognition and Machine Learning written by King-Sun Fu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the Proceedings of the US-Japan Seminar on Learning Process in Control Systems. The seminar, held in Nagoya, Japan, from August 18 to 20, 1970, was sponsored by the US-Japan Cooperative Science Program, jointly supported by the National Science Foundation and the Japan Society for the Promotion of Science. The full texts of all the presented papers except two t are included. The papers cover a great variety of topics related to learning processes and systems, ranging from pattern recognition to systems identification, from learning control to biological modelling. In order to reflect the actual content of the book, the present title was selected. All the twenty-eight papers are roughly divided into two parts--Pattern Recognition and System Identification and Learning Process and Learning Control. It is sometimes quite obvious that some papers can be classified into either part. The choice in these cases was strictly the editor's in order to keep a certain balance between the two parts. During the past decade there has been a considerable growth of interest in problems of pattern recognition and machine learn ing. In designing an optimal pattern recognition or control system, if all the a priori information about the process under study is known and can be described deterministically, the optimal system is usually designed by deterministic optimization techniques.
