摘　　要：本文针对励磁系统的经典PID算法需要被控对象的精确模型、在非线性系统中的性能不够理想这一缺点,分析了船舶柴油发电机组的控制。结合模糊控制和经典PID控制,设计同步发电机励磁系统的模糊PID控制器.模糊推理机的输入为船舶发电机端电压的偏差及其变化率经模糊化处理后的模糊量。在Matlab环境下进行仿真,结果表明模糊PID控制器使发电机的端电压更加稳定,具有较好的静态和动态性能。For accurate model of the object required by typical PID algorithm to research excitation system and the poor performance of nonlinear system, this paper analyzes the control mode of the diesel generator, designs an fuzzy PID control controller combined with PID control and fuzzy control aimed at the synchronous generator excitation system. The input of fuzzy inference engine is the deviation of the terminal voltage and change rate after fuzzy dispose. This model is simulated in matlab. The results show that when using fuzzy PID controller, better static and dynamic characterisitcs about terminal voltage of synchronous generator can be gotten.
