摘　　要：依据模糊理论和常规PID控制规律的基本特点,结合现代大型水力发电工程实际需求,提出了一种基于Mamdani模型的模糊PID控制方法.在建立励磁控制系统简单模型的基础上,通过引入Mamdani模型的模糊规则对PID控制参数进行修正,实现同步发电机励磁系统在全工况下的优化控制,并利用Matlab进行仿真,研究分析表明,新方法与常规PID方法相比具有较好的控制效果,为模糊PID控制在大型同步发电机励磁控制的应用提供一种新思路.According to the fuzzy theory and the conventional proportional-integral-derivative（PID） control principle,a fuzzy control method based on Mamdani model for the excitation control system was presented,when the practical needs of the modern water conservancy and hydropower project were considered.On the basis of the simple model for the excitation control system,this method can realizes the optimal control of the excitation control system under full conditions by correcting the PID control parameters using the fuzzy rules of the Mamdani model.A comparative simulation with Matlab has been accomplished. Through the analysis of the results,it is concluded that the new controller can operate better than the conventional PID controller.It provides a new thought for the fuzzy PID control method to be applied in the excitation control system of the large synchronous generator.
