This unique book presents an analytical uniform design methodology of continuous-time or discrete-time nonlinear control system design which guarantees desired transient performances in the presence of plant parameter variations and unknown external disturbances. All results are illustrated with numerical simulations, their practical importance is highlighted, and they may be used for real-time control system design in robotics, mechatronics, chemical reactors, electrical and electro-mechanical systems as well as aircraft control systems. The book is easy reading and is suitable for teaching.A Student Solutions Manual along with a set of Matlab-Simulink files can be downloaded from http://ac.cs.nstu.ru/~yurkev/books.html.Contents:Regularly and Singularly Perturbed SystemsDesign Goal and Reference ModelMethods of Control System Design Under UncertaintyDesign of SISO Continuous-Time Control SystemsAdvanced Design of SISO Continuous-Time Control SystemsInfluence of Unmodeled DynamicsRealizability of Desired Output BehaviorDesign of MIMO Continuous-Time Control SystemsStabilization of Internal DynamicsDigital Controller Design Based on Pseudo-Continuous ApproachDesign of Discrete-Time Control SystemsDesign of Sampled-Data Control SystemsControl of Distributed Parameter SystemsReadership: Graduate students, academics and researchers in real-time nonlinear control system design applied to robotics, aircraft, and electrical and mechanical systems.
