(c) C A feedback loop is added to the system with gain Kp as shown in Figure Q2c. 5 3s + 2 0.2 0.45 + 1 KE Figure Q2c System with Feedback Loop i) Design Kf so that the closed-loop system achieves critical damping. 4 marks ii) iii) Why is it not possible to create an underdamped second order system from two stable first order systems in series? 1 mark On a zero-pole map show the location of the poles of the system for Kp = 0 (i.e. no feedback), Kp = Kcritical (i.e. the value that results in critical damping calculated in i), and Ke = 2. 3 marks The percentage overshoot of a system is given by the iv) TE equation OS = 100 e 1-32 Assuming the specification for the system requires the fastest rise time possible whilst limiting overshoot to less than 10%, what should the value of 3 be set as and, hence, what should the gain K: be set as? 2 marks
