Control Systems Engineering (2/E) I.J. Nagarath and M. Gopal The book provides an integrated treatment of continuous-time and discrete-time linear and continuous-time nonlinear systems for two courses at undergraduate level or one course at undergraduate level and one course at postgraduate level. The stress is on the interdisciplinary nature of the subject and examples have been drawn from various engineering disciplines to illustrate the basic system concepts. A strong emphasis is laid on modelling of practical systems involving hardware; control components of a wide variety are comprehensively covered. Time and frequency domain techniques of analysis and design of control systems have been exhaustively treated and their interrelationship established. The concepts and criteria of stability are progressively built and interspersed at suitable locations culminating in the generalized criteria of Liapunov and Popov. A chapter on sampled-data control systems covering analysis, stability and design has been added in this edition. Modern approaches are introduced through a full chapter on state variables for both continuous-and discrete-time systems; it includes observer and pole placement design. A new chapter on optimal control gives both transfer function and time domain approaches. The optimal linear regulator problem is treated through dynamic programming. This book ends with a chapter on nonlinear control systems and their analysis via phase-plane and describing function techniques. Control Systems Naresh K. Sinha An introduction to Control Systems, this book provides the reader with the basic concepts of control theory as developed over the years in both the frequency domain and the time domain. The opening chapters of the book present a unified treatment of modelling of dynamic systems, the classical material on the performance of feedback systems based on the transfer function approach and the stability of linear systems. Further, various types of frequency response plots and the compansation of control systems have been presented. In particular, the trial-and-error approach to the design of lead compensators, as found in most textbooks, has been replaced by a direct method developed in the late 1970?s. Moreover, the design of pole-placement compensators using transfer functions, the counterpart of the combined observer and state feedback controller, has been included for the first time in a book appropriate for undergraduate and practising engineers. This book is an attempt to aid the student remove the drudgery out of numerical computations, along with numerous worked examples and drill problems with answers to help the student in mastering the subject.

This book is intended for researchers in process control and applied mathematics. It can also serve as a textbook for graduate students interested in nonlinear control theory. After discussing the basic design method of Model Reference Nonlinear Controller (MRNC), the book deals with the incorporation of explicit integral and derivative actions in the control law. Extension of the method to systems with relative order two and higher is provided. The design of series cascade MRNC systems and parallel cascade MRNC systems are given. Exlensions of MRNC for systems with significant measurement dynamics or actuator dynamics are made. The design method of MRNC for systems with delay in measurement or in actuator is provided. Simulation studies on several nonlinear processes prove the effectiveness of the MRNC. The auther received B.E. (chemical) in 1975 from Annamalai University and M.E. and Ph.D. from I.I.Sc., Bangalore in 1977 and 1984 respectively. He had been in the faculty of Chemical Engineering, Indian Institute of Technology, Bombay from 1984 to 1991. He is presently an Associate Professor in the Department of Chemical Engineering, I.I.T., Madras. His main teaching and research interests are in the area of Process Dynamics and control. He has 60 research publications in this area and guided 3 Ph.D. students. He has organized three Q.I.P short term courses related to Advanced Process Control.
