This chapter introduces the concept of ‘closed loop system’ in general terms explaining the basic principles and issues involved. The significance of analyzing open loop performance of the system to determine the degree of stability that can be achieved during closed loop system operation is explained. Various types of response testing of the closed loop systems are discussed and the analytical techniques developed focus primarily on frequency response as the most popular method used by the control engineering community. Real world examples are used throughout to reinforce the concepts as they are developed. The term used to describe the dynamic behavior of the closed loop system is described as the ‘response characteristic’ of the system and can be determined as either transient response or steady state response. The most commonly used tool for expressing the dynamic characteristics of the closed loop control systems, namely the frequency response plot.
