摘　　要：设计了基于位置敏感探测器(PSD)的太阳跟踪器,实现对太阳的自动跟踪。该跟踪器能够适应各种天气,晴天时启动光电跟踪,阴雨天时启动日历跟踪,能够实现方位角在360°范围内,高度角在90°范围内自动跟踪。进行了系统误差分析与实验,实验结果表明:该方法的跟踪精度在±12°,视场角度内为0.1°,各种天气情况下,跟踪器均能稳定地工作,能够达到预期的设计性能。A new sun-tracker based on a PSD sensor is developed. Two stepper motors are used to achieve the track of sun. It can achieve the track under any kind of weather and light-electric track is used in sunny day, and calendar-check track in rainy day. It can realized the automatic tracking in any direction angle of 360°and any height angle of 90°. Analysis of the system error and some experiments are done, experiment results show that the accuracy of this sun-tracker can be limited in 0.1° in ±12° inspect angle. This device can run stably under all weather.
