This book intends to provide a number of worked exercises to aid students in overcoming the difficulties faced in the study and analysis of automatic control systems engineering with the help of step by step illustrations to cover up the gaps which are usually found in text and reference books and which are usually not apparent to the students. The main features of the seventh edition are:• A new chapter on frequency response has been added.• Additional problems taken from question papers of various universities have been added in all chapters.• All chapters have been thoroughly checked and revised to remove the errors.• Minimum essential theory at the start of each chapter serves as guide and reference.• Problems have been solved with explanations in detail to bridge the gap and to obtain experience in applying the principles with their different ramifications.The seventh edition is an ideal book for the undergraduates and for the students appearing in competitive examinations.AK Jairath ME, FIE, FETE iS Head, Department of Electrical Engineering, has been a Chief Engineer in the Army and Deputy Director of Amity School of Engineering and Technology, Noida, UP.
