• Sommario/riassunto: One of the few books that focuses on practical control theory for high performance systems, succinctly presented for ease of consumption, with illustrative examples using data from actual control designs.This book serves as a practical guide for the control engineer, and attempts to bridge the gap between industrial and academic control theory. Frequency domain techniques rooted in classical control theory are presented with new approaches in nonlinear compensation that result in robust, high performance closed loop systems.
