A newly designed decoupler can simplify complex system into two independent control loops for two-input-two-output(TITO)plant.The frequency analysis is adopted to reduce the order of the de-coupled loop model,on basis of which the controller is designed for each loop.This method can improve the robustness and stability of the control system.Result shows that the proposed controller of TITO plant with long delays for set-point response is effective and feasible.
