Time Response Analysis
7.1 INTRODUCTION
Time response analysis is also called time domain analysis. Here, we study the response, i.e. the output as a function of time.
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.
The transient state of the system remains for a very short time while steady-state is that stage of the system as time t approaches infinity. A feedback control system has the inherent capabilities that its parameters can be adjusted to alter both its transient and steady-state behaviour. In order to ...
