This book provides new insight on the problem of closed-loop performance and oscillations in discontinuous control systems, covering the class of systems that do not necessarily have low-pass filtering properties. The author provides a practical, yet rigorous and exact approach to analysis and design of discontinuous control systems via application of a novel frequency-domain tool: the locus of a perturbed relay system. Presented are a number of practical examples applying the theory to analysis and design of discontinuous control systems from various branches of engineering, including electro-mechanical systems, process control, and electronics.
Discontinuous Control Systems is intended for readers who have knowledge of linear control theory and will be of interest to graduate students, researchers, and practicing engineers involved in systems analysis and design.

From the reviews:“The purpose of this book is to present a new frequency domain theory of discontinuous control systems in which the control systems are viewed and studied as servo systems. … This book is primarily a research monograph, as it is devoted only to frequency domain theory of discontinuous control systems. … it also has many features of textbook, as the theory presented covers a relatively large classic nonlinear control area. The book, therefore, can be used by researcher, practitioners, and undergraduate and graduate students.” (Ion Bogdan, Iasi Polytechnic Magazine, Vol. 21 (1/4), March/December, 2009)
