please solve as matlab code. The system in Figure 3 comprises a motor and a contoller. The performance requirements entail a steady state error for ramp input r(t) Ct, smaller than 0.01C. Here, C is a constant. The overshoot for step input must be such that P.0. 5% and the settling time with a 2% error should be T, 2 seconds (a) Based on rlocus function, write a piece of MATLAB code which establishes the controller.
