WebHere damping ratio is always less than one. Critically damped A critically damped response is the response that reaches the steady-state value the fastest without being underdamped. It is related to critical points in the sense that it straddles the boundary of underdamped and overdamped responses. Here, the damping ratio is always equal to one. WebThe 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 …
