Consider the control system in figure 3, Assume the controllers, PID1 and PID2 is Proportional – Integral (PI), get the close loop transfer function for the system. TF = ii. By using Routh's stability criterion, please get the value of Kp that makes the system marginally stable. The critical gain Kcr is equal to Kp. Kcr = iii. By apply a Ziegler-Nichols tuning rule (method 2), determination of the values of parameters for Kp, Ti and Td. iv. Obtain a unit-step response curve for the system (Y1(s)). V. Obtain a unit-step response curve for secondary controller, (Y2())
