"Control Systems and Mechatronics" provides the concepts of control systems in a concise manner. Concepts of block diagram and signal flow diagram are illustrated with many problems. Various types of systems encountered from control point of view are described in detail. Concepts of time domain and frequency domain analysis of control systems are presented lucidly with common characteristics and tools. Stability of a control system and its importance is given with illustrations. Nonlinear and digital control aspects as a modern control system theory topics are thoroughly dealt with. A brief introduction to Mechatronics in the Ninth chapter discusses the role of control systems in the modern world. Some study and practical experiments under Mechatronics Laboratory presented in the last two chapters would help in understanding application areas of Control systems and Mechatronics.
