This book is intended for undergraduate and first-year graduate courses of all engineering streams. It provides the basic concepts of analysis and design of discrete-time systems. It covers the theory and applications of digital control systems, assuming knowledge of matrix algebra, difference equations, Laplace/Z-transforms, and the basic principles of continuous-data control systems. Although the chapters are written in the digital domain, the principle is the same for both the continuous-time control and the discrete-time control. Key Features Introduces special topics on robust and H-infinity control Contains a unified presentation of the concepts of digital control theory Includes numerous illustrations and solved examples Provides the importance of MATLAB for computation Comprises additional questions and objective-type questions on control systems About the Author Dr V. I. George is currently the Registrar of Manipal University, Jaipur. Formerly, he was Professor and Head of the Department of Instrumentation and Control Engineering, Manipal Institute of Technology (MIT), Manipal. He did his B.E. from Mysore University and completed his M.Tech. from National Institute of Technology, Calicut. His doctoral thesis, which he earned from National Institute of Technology, Tiruchirappalli, was on Robust Control of Dynamic Systems. At MIT, Dr George took the initiative to introduce postgraduate programmes in Control Systems and Astronomy and Space Engineering. His teaching experience spans more than 27 years and he has the honour of organizing many national and international conferences and workshops. He has published more than 75 research papers in the peer reviewed national and international journals and conferences. He is a fellow of Institution of Engineers India, fellow of Systems Society of India, member of IEEE, and life member of ISTE. Dr C. P.
