Design of Main Steam Temperature Cascade Control System Based on Fuzzy Self-tuning PID Controller

摘要：

To obtain perfect performances of the main steam temperature control system, a new scheme is proposed. The scheme substitutes fuzzy self-tuning PID controller for the main regulator of cascade control system. The controller is composed of fuzzy controller and PID controller. According to the error and error rate of the control system and fuzzy control rules, the fuzzy controller can online adjust the three parameters of the PID controller, then alter the output of the fuzzy self tuning PID controller to maintain the main steam temperature. The results show that the proposed control scheme has smaller overshoot, shorter settling time, better capacity of anti-disturbance and stronger robustness than the conventional PID cascade control.
