摘　　要：传统的太阳跟踪方式多采用光电跟踪或视日跟踪,跟踪精度低,存在累积误差。为了改进对太阳的跟踪精度和消除累积误差,计算各种太阳角,提出以光电跟踪为主要的跟踪方式,同时设置视日跟踪控制,通过两种跟踪方式互补,可以让光伏阵列在昼夜更替以及任何气候条件下得到稳定而可靠的跟踪控制,完成光伏阵列跟踪控制过程的设计。traditional way of the sun track ing control usually sparately takes the Way photoelectric tracking or sun angle tracking control system.but it always lower tracking precision, large comulative errors.in order to improve the accuracy of tracking the sun, analysis the motion law of the sun, and a calculation of the sun angle is proposed, proposed electro-optical tracking as the major tracking mode while the sun trajectory tracking as additional mode on unusual weather conditions, on the one hand, electro-optical tracking can give fuU play to the advantage of high accuracy,on the other hand ,the system can still achieve tracking on cloudy weather conditions.
