کنترل مقاوم سرعت سیستم توربین بخار با استفاده ازتنظیم IMC کنترل کننده PID بهبود

This papers explains the method of obtaining proportional, integral and derivative (PID) parameters for singe loop control of turbine speed control system by approximating the feedback form of an IMC controller with elimination of higher order terms in the controller form to classical PID form for Robust operation. The IMC has single tuning parameter to adjust the performance and robustness of the controller. The proposed method is the efficient in set-point tracking and disturbance rejection and controlling the overshoot, stability and dynamics of the speed control of turbine. The results obtained in simulated environment implemented in LabVIEW show the improvement in the performance compared to PID tuning using convention techniques like Ziegler-Nicholas (Z-N) rules and tuning technique proposed by Y. Lee et.al.
