Disturbance Attenuation for Uncertain Control Systems

This book presents a survey on recent attempts to treat classical regulator design problems in case of an uncertain dynamics. It is shown that source of the uncertainty can be twofold:(i) The system is under the influence of an exogenous disturbance about which one has only incomplete - or none - information.(ii) A portion of the dynamical law is unspecified - due to imperfect modeling.Both cases are described by the state space model in a unified way&quote;Disturbance Attenuation for Uncertain Control Systems&quote; presents a variety of approaches to the design problem in the presence of a (partly) unknown disturbance signal. There is a clear philosophy underlying each approach which can be characterized by either one of the following terms: Adaptive Control, Worst Case Design, Dissipation Inequalities.
