Type 0 Systems Examples


Let's say that we have a system that looks like this:

where G(s) is:

1 --------------- (s + 2)(s + 3)
Let's look at the closed-loop response for this system when we use different inputs:

Step Input

Our steady-state error is a constant.

Ramp Input

Our steady-state error is infinity (the error continually increases as time goes to infinity).

Parabolic Input

Our steady-state error is infinity (the error continually increases as time goes to infinity).
