The previous solutions are posted on screenshot. please refer to them for gain value. solve : An integrator is added to the PD controller, leading to a PID controller C(s) = kp +ki/s + kds. Keep the PD controllers gains kp and kd from above, and plot the closed-loop poles as the gain ki varies from 0 ! 1 (Hint: The closed-loop poles satisfy 1 + P (s)C(s) = 0, translate this to Evan’s form 1 + kiG(s) = 0). Determine gains such that a load disturbance is rejected in about 10 time units, while keeping the amount of overshoot (from r to y) under 20%. Why can ki not be too large?
