The steady-state error for a system is defined as:
R(s) = Input
G(s) = open loop transfer function
H(s) = feedback gain = 1 for unity feedback system
Analysis:
For a unit step input, we have:
The steady-state error becomes:
1 + G(0) = 10
G(0) = 9
Again we have the input as:
r(t) = 10 [u(t) – u(t - 1)]
=
∴ The steady-state error for the input will be:
=
Important Points
The shifting in input signal does not affect the steady-state error.
