Available in PDF, EPUB and Kindle. Book excerpt: In adaptive control the goal is to deal with systems that have unknown and/or time-varying parameters. Adaptive control techniques have been developed since 1950's and most results were proven in the cases when the time-variations were non-existent or slow. However the results pertaining to systems with fast time-variations are still limited, in particular, when it comes to plants with unstable zero dynamics. In this work we adopt the controller design technique from the area of gain scheduling, where the time-varying parameter is assumed to be measurable. We propose the design of a nonlinear periodic controller, where in each period the state and parameter values are estimated and an appropriate stabilizing control signal is applied. It is shown that the closed loop system is stable under fast parameter variations with persistent jumps: the trajectory of the closed loop state in response to the initial condition is bounded by a decaying exponential plus a gain times the size of the noise. Our approach imposes several constraints on the plant; however, we show that there exists at least one interesting class of systems, which includes plants with unstable zero dynamics, that can be stabilized by our controller.

This book was released on 2018 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: In adaptive control the goal is to deal with systems that have unknown and/or time-varying parameters. Most techniques are proven for the case in which any time-variation is slow, with results for systems with fast time-variations limited to those for which the time-variation is of a known form or for which the plant has stable zero dynamics. Here we propose a new adaptive controller design methodology for which the time-variation can be rapid. While the plant is allowed to have unstable-zero dynamics, it must satisfy several structural conditions which have been proven to be necessary in the literature; we also impose some mild regularity conditions. The proposed controller is nonlinear and periodic, and in each period the parameter values are estimated and an appropriate stabilizing control signal is applied. Under the technical assumptions that the plant is relative degree one and that the plant uncertainty is in terms of a single scalar variable, it is proven that the closed loop system is stable under fast parameter variations with persistent jumps.

Available in PDF, EPUB and Kindle. Book excerpt: In adaptive control the goal is to deal with systems that have unknown and/or time- varying parameters. An adaptive controller typically consists of an LTI compensator together with an identifier or a tuner which is used to adjust the compensator parameters. A common approach to tuning is to invoke the Certainty Equivalence Principle, where at each instance of time the estimated plant parameters are assumed to be correct and the controller gains are updated accordingly. In this work we consider the first order case. We use the Certainty Equivalence approach to periodically estimate the plant parameters and then update the control action in order to provide stability. The data from first two steps are used to estimate the system parameters for the next two steps; the approach works by using a nominal control law and adding a small perturbation to the gain. The controller is proven to be noise tolerant, and we are able to prove a linear-like bound on the closed-loop behavior.

Book Synopsis Adaptive Modeling and Control by : Frederic D. Powell
Download or read book Adaptive Modeling and Control written by Frederic D. Powell and published by . This book was released on 1972 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a variety of situations, the parameters which define a dynamic plant are poorly known, are unknown, or may change in an unpredictable way during operation. Improved control performance can be achieved if the unknown parameters' values are identified. Research conducted under these contracts studied the application of adaptive techniques to parameter identification and control of linear, nonlinear, and time-varying plants. The report outlines the research accomplished on open and closed-loop methods of parameter identification for linear plants, and for nonlinear plants using a combination of nonlinear quantizing and piecewise-linear operations. Adaptive inversion, decorrelation, orthogonalization and normalization are discussed. Adaptive control methods using a two-time-scale principle are explored. (Author).

Book Synopsis Adaptive Control Tutorial by : Petros Ioannou
Download or read book Adaptive Control Tutorial written by Petros Ioannou and published by SIAM. This book was released on 2006-01-01 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designed to meet the needs of a wide audience without sacrificing mathematical depth and rigor, Adaptive Control Tutorial presents the design, analysis, and application of a wide variety of algorithms that can be used to manage dynamical systems with unknown parameters. Its tutorial-style presentation of the fundamental techniques and algorithms in adaptive control make it suitable as a textbook. Adaptive Control Tutorial is designed to serve the needs of three distinct groups of readers: engineers and students interested in learning how to design, simulate, and implement parameter estimators and adaptive control schemes without having to fully understand the analytical and technical proofs; graduate students who, in addition to attaining the aforementioned objectives, also want to understand the analysis of simple schemes and get an idea of the steps involved in more complex proofs; and advanced students and researchers who want to study and understand the details of long and technical proofs with an eye toward pursuing research in adaptive control or related topics. The authors achieve these multiple objectives by enriching the book with examples demonstrating the design procedures and basic analysis steps and by detailing their proofs in both an appendix and electronically available supplementary material; online examples are also available. A solution manual for instructors can be obtained by contacting SIAM or the authors.
