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 cancelled 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.
