Time Response Analysis
7.1 INTRODUCTION
Total time response c(t) of a control system consists of transient response (dynamic response) ct(t) and steady state response css (t).
|
c(t) = ct(t) + css(t) |
where |
c(t) = total time response |
|
ct(t) = transient response |
|
css(t) = steady-state response. |
A transient state of the system remains for short time while steady-state is that stage of the system as time t approaches infinity. A feedback control system has the inherent capability that its parameters can be adjusted to alter both its transient and steady-state behaviour. In order to analyse the transient and steady-state behaviour of control systems, we obtain a mathematical model of the system. For any specific input signal, a ...
