This book provides a comprehensive coverage of the subject for undergraduate students (BE/BTech) of engineering disciplines. 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.
Spread in 10 chapters, the book broadly deals with:

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
