Type 2 Systems Examples


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

where G(s) is:

(s + 1) (s + 3) ------------------- s^2 (s + 2)(s + 3)
Note that we are using a different numerator in our transfer function in order to make sure we have a stable closed-loop system

Let's look at the closed-loop response for this system when we use different inputs:

Step Input

Our steady-state error is zero.

Ramp Input

Our steady-state error is zero.

Parabolic Input

Our steady-state error is constant, but it's kind of hard to see. Therefore, we will zoom in to show this steady-state error:
