模糊整定PID控制在水电机组中应用研究

传统的水电机组PID控制不能根据系统的动态过程自动调整控制参数，系统在工况变化时很难达到较好的控制效果。本文提出一种改进的智能自适应模糊PID控制系统，模糊推理输出在线修改PID参数，并探讨了如何整定PID参数以达到最优控制效果。仿真实验表明这是一种有效的控制策略，尤其在启停机过程及负载扰动过程较传统PID控制具有更好的鲁棒性和稳定性。

Study on Fuzzy PID Controller for Water Power Generating Unit

In order to overcome the shortcoming of the conventional PID controller of water power generating unit, a new self-tuning PID control method is proposed. The output of fuzzy reasoning can adjust PID parameter in the process of control. The way of adjusting PID parameter to obtain the optimal control effect is discussed. Simulation result shows that the designed.fuzzy PID control strategy is better then traditional PID control strategy and fuzzy PID control system is of good robustness and stabilization.
