Modelling a Control System—Transfer Function Approach

2.1  INTRODUCTION

We have discussed in the previous chapter that a control system consists of a number of sub-systems. All the sub-systems work in unison to achieve a desired output for a given input. Mathematical modelling of sub-systems and also of the whole system is required for carrying out performance studies. In this chapter, modelling of a control system using transfer function approach has been dealt with.

2.2  TRANSFER FUNCTION

In control theory, transfer functions are commonly used to characterize the input-output relationship of components or systems that can be described by linear, time-invariant differential equations. The relationship between input and output is represented ...
