Question 3 A closed loop speed control system is shown below For the open loop the time response was recorded for a step input of magnitude o.2 a) Use the graph to determine the parameters r and Kn (from the recorded time response). 2.5 1.5 0.5 50 001 002 0.03 0.04 0.05-0.06 0.07 0.08 009 Seconds Determine the desired closed-loop poles that achieve a damping ratio of b. = 0.707 and a settling time of 0.02 second. Hint: You may calculate the poles as: su” ζ o'n ± j awl -(i and settling time as Ts ~
