摘　　要：实验系统由输入设备(光敏三极管等)、控制设备(单片机)和输出执行设备(舵机)构成。分布在180度方向范围内的多个光敏三极管接收不同角度的光线强度,转换为电信号。单片机将该电信号与输入的控制脉冲信号进行比对,产生纠正脉冲信号,并驱动电机反向或正向转动,使得太阳板时刻与光线垂直,提高了太阳板光电转换效率。The experimental system constituted three units, the input device （the phototransistor）, the control equipment （the Micro Control Unit）, and the equipment of output and implementation （the steering machine）. Multiple photo transistor within the direction of 180 degrees received light intensity of the different angles, and converted to electrical signals. The Micro Control Unit compared inputting pulse signal. The pulse signal was generated by Micro Control Unit compare the input signal and con- trol pulse signal,and drived the steering machine to rotate by counterclockwise or clockwise. In this way, to keep the solar panels always plumb to the sunshine.
