QUESTION 3 A feedback system is shown in Figure 2. The desired transient response characteristics of the system when subject to a unit-step input is an undamped natural frequency of 4.6 rad/s and a damping ratio of 0.42 R(s) + 1 s(s+ 2.7) Figure 2. Feedback system for Question 3. s+Zc s+ Pc State your values for K, ze and pc. Ge(s) = K a. Determine the location of the desired dominant closed-loop poles. The desired dominant closed-loop poles will not lie on the root locus, you do not need to prove this. b. Using root locus method, design a lead compensator so that the desired transient response characteristics are met. Begin your design by placing the lead compensator's zero at s = -3.5 Assume the lead compensator will be designed in the form C(s)
