B-5-3.Consider the closed-loop system given by C(s) R(s) 07/1 s² + 25@ns + wh/ n Determine the values of? and w so that the system responds to a step input with approximately 5% overshoot and with a settling time of 2 sec. (Use the 2% criterion.)

QUESTION 17 Consider again the control system illustrated in Figure Q16a and Figure Q16b. Assume that C(s)=10. What is the phase margin of the loop transfer function? Express your answer in degrees, but do not type any units, and round to the closest multiple of 15 degrees

A feedback system has the closed loop transfer function shown below. Find K2 so that the settling time t,=0.2 seconds for a 1% tolerance. C(s) R(s) 100K1 20s(1 + 0.5s) + 100K1+(100)(20)K25
