摘　　要：为了提高太阳能利用率,设计了一种基于ARM7的太阳自动跟踪简易控制系统;该系统利用32位ARM嵌入式微处理器LPC2131为控制器,采用光电跟踪和定时跟踪相结合的控制方式;以步进电机作为驱动机构,通过控制跟踪的机构水平、俯仰两个方向运动,实现对太阳的全跟踪;仿真和试验结果表明,该控制系统的跟踪精度误差在1°以内,能够满足太阳自动跟踪的需要,且性能稳定、功能丰富、成本较低,可以为太阳能飞行器的太阳自动跟踪控制工程研制提供参考依据。To improve the utilization of solar energy, a new type of solar tracking simple control system was designed based on ARM7. The tracking system used a 32bite ARM （Advanced RISC Machines） embedded microprocessor as controller, optical tracking combined with timing tracking as control method; and stepping motor as the executing agency. The entire track towards the sun was realized by controlling on the two directions of Level and pitching. Simulation and test showed that tracking accuracy error in 1°within, meeting the needs of the so lar automatic tracking. Respectively, the system possessed the features of stability performance, multi--functions and low cost. The design would provide valuable reference for the solar automatic tracking engineer.
