Hi,
I have question where I am asked to find the % overshoot of a system based only on its transfer function.
T(s) = 15(s+2.1)
(s+2)(s2+4s+29)(s2+2s+50)
I'm assuming I need to use second order assumptions and then find the damping ratio (zeta) to find the %OS, but this equation looks a little complicated for that.
I noticed that the numerator (s+2.1) could be canceled with the (s+2) term in the denominator because they're similar. Am I allowed to do that?
Then I'm still left with two quadratic equations on the bottom.. I still can't see how you could approximate the %OS.
