摘　　要：综合分析了聚光器跟踪控制精度和综合性能对碟式太阳能发电系统的重要作用和影响,介绍了一种高精度碟式太阳能聚光器跟踪控制系统的构成和工作原理,建立了核心控制器PLC中的PID及自适应模糊PID控制的Matlab/Simulink仿真数学模型,比较分析了在单位阶跃信号和扰动作用下不同控制策略时跟踪控制系统的响应特性.结果表明:自适应模糊PID控制下碟式太阳能聚光器跟踪控制系统不仅具有良好的跟踪控制精度,也具有抗干扰能力强和稳定性能好的优点,大大提高了碟式太阳能聚光器跟踪控制系统的综合性能.The concentrator tracking control accuracy＇s important action generation system were high - precision dish comprensolar renensively analysed, concentrator tracking the structure and working and influence on the dish solar power principle were introduced, which of a control system, the Matlab/Simulink simulation mathematical model of the PID and the self - adaptive fuzzy PID control which in the core controller （PLC） were established, the characteristics of the tracking control system were comparatively the unit step signal and disturbance signal were given to the analysed, under different control strategies when system. The results show that the dish solar concentrator tracking control system under self- adaptive fuzzy PID control not only has a good tracking accuracy, but also has strong interference ability and good stability, greatly enhanced the comprehensive performance of the dish solar concentrator tracking control system.
