4) A unity feedback control system shown in Figure 2 has the following controller and process with the transfer functions: G contr (S)=Kp+KDS 10 = process (S) s² (s+10)(s+5) a) Obtain the open- and closed-loop transfer functions of the system. b) Obtain the stability conditions using the Routh-Hurwitz criterion. c) Setting by trial-and-error some values for K², and KD, obtain the time response for minimum overshoot and minimum settling time by Matlab/Simulink.
