Control Systems

This book provides on introduction to control systems, their functions and their role in engineering design. It trains students carry out practical engineering on all types of control systems. It covers basic analysis, operating and design techniques as well as hardware and software implementation. Relevant numerical questions of GATE have been solved to make the book suitable for the students appearing in various entrance examinations. All the solved and unsolved problems in this book are tested and illustrate the topics thoroughly. Emphasis is laid on the pedagogical aspects of the subject. Topics covered include: basic concepts of control systems, input-output relationship of the system, mathematical modeling of physical systems including mechanical and electrical systems, force-voltage and force-current analogy systems, block diagram representation of systems, time response analysis, stability of control systems and Routh-Hurwitz criteria, root locus method, frequency domain analysis, polar plot, compensators and PI, PD, PID controllers, state variable approach, and, concepts of controllability and absorbability. This book will be useful for B.E & B.Tech students.
