Dual-Axis Tracking Control Design and Optimization of Solar Concentrator

针对聚光光伏跟踪控制的要求,设计了一种改进型的太阳能双轴跟踪控制系统,并对控制系统进行了优化.系统采用一种新型太阳位置算法ENEA(2007),高度角和方位角的最大误差不超过0.002 7°;硬件平台采用STM32系列芯片作为系统的控制核心,在电机控制追踪精确度方面进行了优化.经现场实验测试,该控制系统运行稳定可靠,整体误差较低.

In view of the requirement of photovoltaic tracking control for concentrator,a kind of advanced solar dual-axis tracking control system was designed and optimized.In the system a new type of solar position algorithm ENEA（2007）was used and the maximum error of azimuth and zenith is below 0.002 7＆#176;.In the hardware platform,the series of STM32 chip was adopted as the core control system,and the tracking reliability of the motor control was also optimized.The field testing and measurement show that the operation of control system is stable and reliable,and the overall error remains at a low level.
