A feedback system subjected to disturbance input is given below. Since the transfer function of the controlled system is given as Gp(s) = 8 s(35+2) a) If the system is controlled by a ratio type (G(s) =Kp) Controller with a gain value of 24, what will be the damping ratio, natural frequency and dynamic behavior of the system? If the unit ramp reference input affects the system, obtain the permanent state error caused by the reference input. b) If the system is controlled by a (G (s) = Kp+ks) Controller such as proportional plus derivative, what should be the derivative gain that will ensure that the Same proportional gain value makes the system critically damped? c) Considering the situation in b); What will be the total steady state error of the system if the unit ramp reference input and the unit step disturbance input act RCS) D(s) G(s) asperox.com.tr OD ((s) S(35-2).
