domain we used the second order system as a model to define various criteria such as percentage overshoot, rise time, settling time, etc. Although these criteria related specifically to second order systems we also found them useful for analyzing more complex systems. The basic assumption was that for most systems there is a dominant pole pair that serves to characterize the overall behavior of the larger, more complex system. We developed relationships for settling time, percentage overshoot and peak time in terms of the undamped natural frequency Z and damping ratio ] n of the second order system. In analogous fashion we will relate the second order frequency response to undamped natural frequency and damping ratio and develop various criteria for evaluating closed loop system frequency responses. First consider the following second order system with two real
