ABSTRACT
This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book introduces the concepts of control systems, discusses examples of control systems, and thus provides the motivation for the material. It develops different techniques of obtaining and expressing mathematical descriptions for various physical systems, which include mechanical, electrical, electromechanical, thermal, chemical, and hydraulic systems. The book introduces, develops, and analyzes the principles of feedback control systems and illustrates their characteristics and advantages. It deals with the root locus design techniques, explains the procedure of creating root loci and outlines their uses. The book seeks to investigate the steady state response of a dynamic system to sinusoidal inputs as the frequency varies. It addresses the issues involved in the design, analysis, and implementation of digital controller. The book explores advanced topics and issues involved in the design and analysis of control systems are addressed.
