A control system directs, regulates, manages and commands the behavior of systems and devices using control loops. Control systems can range in size and functionality from the level of a home heating controller which uses a thermostat to control a domestic boiler to massive industrial control systems which control entire processes or machines. Feedback control and automation are two important aspects of control systems. Some of the techniques used in the design of advanced control systems include adaptive control, dynamic-optimizing control, learning control and multivariable-noninteracting control. Computer technology is applied to industrial control problem for supervisory for optimizing control, hierarchy control and direct digital control. This book unfolds the innovative aspects in the design of control systems. Also included in this book is a detailed explanation of the various concepts, implementation and applications of control systems. It will help the readers in keeping pace with the rapid changes in control engineering.
