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. WebHence, the line from the origin through p 1 forms a line of constant damping ratio. This allows us to define a region of acceptable system damping by requiring that the poles lie within a specified region on the pole-zero map.
