Time response c(t) for first order control
system to unit step input is shown (where
t is the time constant unit step signal).
c(t) = (1-e --/ t) u(t)
c(t) = ett
u(t)
Oc(t) = T (1-e-t/u(t)
c(t) = (1+e --/ 7) u(t)

Answer:
Response of the First Order System - In this chapter, let us discuss the time ... We know that the transfer function of the closed loop control system has unity ... R(s) is the Laplace transform of the input signal r(t), and. T is the time constant. ... The unit impulse response, c(t) is an exponential decaying signal for positive values Let us consider the effect of both the input r(t) and the initial condition c(0). ... If R(s) = u(t), the unit step function, then the force response (step response) is given (with ... s + 1/τ . In the time domain c(t) = K(1 − e−t/τ )u(t). If the response continued to ... are all measures of performance that are used to design control systems.
