1) Derive the two design equations to determine Kp and Kd to meet the objectives2) Simulate in matlab and plot step response to show results achieved. Include your code and plot. Consider the following closed-loop PD control system controller e(t) k, plant Command r(t) 1 X(t) kas s+10s+20 The design objectives are: Steady state step error<10% Settle time=.5sec
