The book Control System Engineering has been prepared to meet the requirements EEE & ECE Branches of UG and PG students. This book is an outcome of decades of experience the author has in teaching courses on Control Systems for both UG and PG students.
The first chapter deals with introduction to Control Systems. It covers Open and Closed Loop Systems, Classification based on number of inputs and outputs. It also introduces Linear and Non-Linear as well as Continuous and Discontinuous systems. Second chapter covers Input-Output relations including block diagrams and signal flowgraphs. Third chapter deals with mathematical modeling of systems including Electrical Networks, Linear Mechanical Systems, Mechanical Coupling Devices and Electro-mechanical Systems. The fourth chapter exhaustively covers Time Domain Analysis. Fifth chapter covers Stability Concepts. This includes stability and impulse response, necessary and sufficient conditions for stability of control systems. It also covers stability criteria for stability and their application to linear feedback systems. Root-Locus technique is comprehensively covered in this chapter. Sixth chapter deals with Frequency Domain Techniques. The coverage includes Nyquist Stability Criterion, Polar and Bode Plots, Frequency domain specifications and characteristic of a Second Order Control Systems. It also covers Frequency response of General Control Systems. Modern Control Theory is comprehensively covered in seventh chapter. While dealing with the topics, care has been taken to highlight important concepts with illustration and examples maintaining the language as simple as possible. Large number of examples have been worked out of a better understanding of the subject.. Practice exercise problems are provided at the end of each chapter. Recent papers each for EEE and ECE branches have been included to help students.
