This Indian adaptation of the text maintains those aspects of the previous editions that have led to the book being so successful. In addition to introducing a new chapter on Optimal Control Systems, this edition strengthens the coverage by including new sections on Servomechanism, Multivariable Systems, Tuning of PID Controller, and All-Pass and Non-Minimum Phase Systems. Many of the end-of-chapter problems have been revised and new problems have been added. It also includes multiple choice questions based on the questions from various competitive examinations.
