Adaptation In Dynamical Systems

This page intentionally left blank A DAPTATION IN DYNAMI CAL S YS TEMS In the context of this book, adaptation is taken to mean a feature of a system aimed at achieving the best possible performance when mathematical models of the environment and the system itself are not fully available. This has applications ranging from theories of visual perception and the processing of information to the more technical problems of friction compensation and adaptive classification of signals in fixed-weight recurrent neural networks. Largely devoted to the problems of adaptive regulation, tracking and identification, this book presents a unifying system-theoretic view on the problem of adaptation in dynamical systems. Special attention is given to systems with nonlinearly parametrized models of uncertainty. Concepts, methods, and algorithms given in the text can be successfully employed in wider areas of science and technology. The detailed examples and background information make this book suitable for a wide range of researchers and graduates in cybernetics, mathematical modeling, and neuroscience.
