摘　　要：为解决脉冲负载条件下,常规PID调速系统控制的柴油发电机会出现电压波形严重畸变和频率剧烈波动等电能质量问题,本文通过借鉴模糊控制在非线性控制中的优点,提出一种利用模糊PID调速器控制调速系统改善柴油发电机输出电能质量的方法,分析模糊PID控制原理,在Matlab/Simulink中搭建柴油发电机带脉冲负载仿真模型,并针对两种调速系统进行仿真对比。结果表明,在脉冲负载条件下,模糊PID调速系统相较于常规PID调速系统有更好的实时调节性能,能够较好地改善系统电能质量。In order to solve the power quality problems of diesel generator controlled by the conventional PID speed control system under pulsed load conditions,such as serious voltage waveform distortion and severe frequency fluctuations,by referring to the advantages of fuzzy control in nonlinear control,a method of using fuzzy-PID governor for controlling the speed governing system is proposed to improve the power quality of diesel generator.The fuzzy-PID control principle is analyzed.A simulation model of diesel generator with pulsed load in Matlab/Simulink is built,and comparative simulation experiments for the two speed control systems are conducted.The simulation results show that the fuzzy-PID speed control system has better real-time adjustment performance than the conventional PID speed control system under pulsed load conditions,and can better improve the power quality of the system.
