I have a designed feedback control system trying to minimize the overshoot and the setting time. The zeta I (think) ended up with is 0.94. According to this formula:
I am supposed to have a very small overshoot. However the step response of the system looks like this:
The poles are:
0.0000 + 0.0000i (0 is also a zero, so do they cancel?)
-2.0000 + 0.0000i
-0.5313 + 0.1740i
-0.5313 - 0.1740i
-0.5600 + 0.0000i
-0.0600 + 0.0000i
Does that formula apply only for second order system? Or must I have miscalculated something?
