So the modulus margin by definition gives a lower bound of both the gain and phase margin. WebThe phase margin for this system is approximately 95 degrees. The relation, damping ratio = PM/100, only holds for PM < 60. Since the system is first-order, there should be no overshoot. The last major point of interest is steady-state error. The steady-state error can be read directly off the Bode plot as well. did jada pinkett smith attend the oscars 2023
