Simulation analysis of Series Cascade control Structure and anti- reset windup technique for a jacketed CSTR

A method for PID controller tuning based on process models for series cascaded control systems using anti-reset windup technique is proposed in this paper. Closed loop response is obtained using auto tuning of PID controller. This method can be applied to any closed loop stable processes. Closed loop responses of series cascade control loops tuned by the proposed anti-reset windup technique method are compared with the existing cascade control system. Simulation results on nonlinear stable continuous stirred tank reactors is presented to show the efficiency of the proposed controller using anti-reset windup technique.
