Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I am getting confused about how to calculate steady state error in a system.

My particular transfer function is:

G(s)= 4.992/(s^2+3s-1)

Firstly, with an input step am I right in saying that the Steady State error will always be zero?

If so can someone explain the reason behind this, is it because it has negative real parts?

Also, what happens when I apply a ramp input?

An example would be great if possible.

Thanks in advance

Steve
