摘　　要：提出一种时间/传感器双模式互补的太阳跟踪控制方法,并研制出聚光型阳光传感器,提高了太阳跟踪精度。以ARM Cortex-M3为内核的STM32为控制器,设计一套高精度太阳跟踪控制系统,主要由阳光传感器、模数转换芯片MAX197、时钟芯片、光电隔离、驱动、LCD12864液晶、机械部分(含东西方向、南北方向直流电机)组成。经过实验测试及某公司1200 W砷化镓发电系统的实际应用表明,系统跟踪精度达0.1°,能够满足太阳能聚光发电、太阳能热发电、太阳光照明等应用中太阳跟踪要求。A time/sensor dual mode complementary sun tracking control method was proposed and developed concentrating solar sensor was designed which improves the sun tracking performance. Based on STM32 whose core was ARM Cortex-M3,a high-precision sun tracking system was put forward,which was consisted of sun sensor,Analogto-Digital conversion chip MAX 197, clock chip, optical isolation, drive, LCD 12864, the mechanical parts （including east- west direction,the north-south direction DC motor）. Experimental and engineering tests prove the system＇s tracking accuracy was up to 0.1°,which can meet solar applications such as solar concentrating power generation,solar thermal power,sunlight lighting.
