Unformatted text preview: tions are zero. 3. (34pts) A system has the closedloop unit step response depicted in Figure 2. (a) What is the (minimum) system type number of the loop transfer function? Explain your answer. (b) Compute the dominant poles of the closedloop system. (c) Do you think that the closedloop system behaves exactly like a secondorder system (no zeros and only two poles)? Why or why not? (d) Sketch the polezero map of the closedloop system. Indicate on the polezero map how you would move the dominant poles if you needed a shorter settling time without changing the percent overshoot. Step Response Time (sec) Amplitude 1 2 3 4 5 6 0.2 0.4 0.6 0.8 1 1.2 1.4 System: sys Final Value: 1 System: sys Time (sec): 4.25 Amplitude: 1.02 System: sys Peak amplitude: 1.04 Overshoot (%): 4.32 At time (sec): 3.14 Figure 2: Unit step response for Problem 3....
