摘　　要：介绍了同步发电机励磁系统的组成结构,针对传统励磁控制系统采用PID控制器的不足,将模糊控制算法和非特异性细胞免疫原理与传统PID控制相融合的模糊免疫PID控制策略。在Matlab/Simulink仿真环境中建立起仿真模型,分别对励磁控制系统设计了PID控制器、模糊自适应PID控制器、模糊免疫PID控制器并一一进行仿真,通过对比各个策略的仿真波形得出模糊免疫PID控制器在控制性能上优于传统的PID控制器和模糊自适应PID控制器,验证了所提出控制策略的有效性和优越性。Introduction was made to the structure of Synchronous generator excitation system, contrapose the shortcomings of the traditional PID controller, a PID fuzzy immune controller was presented with the combination of fuzzy control and immune feedback mechanism with the convention PID control. Via a simulation model in MATLAB/Simulink environment, emulation was implemented in three ways： PID controller, fuzzy adaptive PID controller and fuzzy immune PID controller. The results showed that the control performance of fuzzy immune PID controller was superior to PID controller and fuzzy adaptive PID controller, the results confirmed the effectiveness and superiority of the control method.
