Modern Control Theories

Fülszöveg

Frigyes Csaki MODERN CONTROL THEORIES Nonlinear, Optimal and Adaptive Systems The volume consisting of eight parts gives a survey of those chapters of modern nonlinear control theory which are important in engineering practice. Time-variant systems are not covered separately but, wherever a generalization is plausible, the characteristic differences between nonautonomous and autonomous systems are pointed out. The first part is an introduction defining the nonlinear and timevariant systems and certain peculiarities of these systems are particularly emphasized. The second part deals with the methods of linearization. Direct time-domain linearization, indirect random-input linearization, harmonic-input linearization, combined harmonic-random-input linearization are discussed. The third part summarizes step-by-step approximation methods. The most important graphical (construction) and numerical (computation) methods used in control engineering are described.

Frigyes Csaki MODERN CONTROL THEORIES Nonlinear, Optimal and Adaptive Systems The volume consisting of eight parts gives a survey of those chapters of modern nonlinear control theory which are important in engineering practice. Time-variant systems are not covered separately but, wherever a generalization is plausible, the characteristic differences between nonautonomous and autonomous systems are pointed out. The first part is an introduction defining the nonlinear and timevariant systems and certain peculiarities of these systems are particularly emphasized. The second part deals with the methods of linearization. Direct time-domain linearization, indirect random-input linearization, harmonic-input linearization, combined harmonic-random-input linearization are discussed. The third part summarizes step-by-step approximation methods. The most important graphical (construction) and numerical (computation) methods used in control engineering are described. The fourth part is devoted to the state-plane and phase-plane methods. In addition to a number of application examples, relay control systems are mainly discussed. The fifth part deals with the stability problems of nonlinear systems. The direct (second) stabilityinvestigation method of Lyapunov,
its fundamentals and important control-engineering versions are described. The Popov frequency-domain theorems concerning absolute stability are introduced. The stability testing of discrete-data nonlinear systems is also treated. The sixth part deals with optimal control systems. Besides the classical calculus of variations and the fundamentals of functional analysis numerical examples are given to illustrate the practical applications. The seventh part explains the fundamentals of the theory of adaptive systems. Finally the Appendix (Part 8) reviews some fundamental theorems of vector analysis and provides a summary of certain theorems concerning state variables and the solution of linear vector differential equations with respect to their utilization.
