Consider the spacecraft single-axis attitude control system shown in Figure CP7.8. The controller is known as a proportional-derivative (PD) controller. Suppose that we require the ratio of KP/KD = 5. Then, develop an m-file using root locus methods find the values of KD/J and KP/J so that the settling time Ts is less than or equal to 4 seconds, and the peak overshoot P.O. is less than or equal to 10% for a unit step input. Use a 2% criterion in determining the settling time.
