Design a feedback system for the system below: Assume all parameter are unity in the MKS system. Mass 1 Kg, Spring Constant = 1 N/m, and Damping coefficient = 1 N*s/m. u₁ k₁ m₁ m2 S 12 a. Using Matlab plot the step response of the output of y and z using a PD controller with y as your feedback. Design your gains for a 10% overshoot. Step size should be 1 meter. Control input U_1. Feedback states y and dy/dt. b. Using the same gains you found in part a. Provide the same step response with the controller using Z as the feedback instead of Y. Control input U_2 and feedback states Z and dZ/dt. Submit Plots for a and b, and the PD gain for your controller.
