摘　　要：为提高太阳能电池光电转换效率,设计了不得一种太阳能双轴全自动聚光跟踪控制系统,使可以放多个太阳能电池模块的框架平台可以跟踪太阳光旋转,并保持框架平台上的太阳能电池与阳光入射角保持垂直,以达到光能的最大获取率。在考虑太阳的运动轨迹模型的基础上,设计出可以同时跟踪太阳轨迹的二轴框架平台结构,方位轴和俯仰轴。在考虑晴天和阴天等复杂天气情况下,设计太阳运行轨迹跟踪方式和光传感器跟踪方式相结合的自适应智能跟踪方法,全自动地准确跟踪太阳的位置,跟踪精度小于0.4°,最大限度的接收太阳能,提高了太阳能光电转换的效率。For improving the conversion efficiency of solar battery module, the high-precision two-axis autonomous solar spotlight tracking control system is designed. The framework platform which places multiple solar battery modules can track the sun rotating, and maintain perpendicular to the sun to achieve the solar battery modules maximum access rate of light energy. Referring to the tracking model of the sun, the two-axis tracking framework platform structure is designed which can track the sun simultaneously, at the azimuth axis and the pitch axis. With considering the complex weather conditions of sunny and cloudy, etc., the sun tracking mode employs adaptive intelligent combination method of tracking mode by optical sensors and accurate tracking the location of the sun by calculations, the tracking accuracy is less than 0.4° to the maximum receive the solar energy, and improve the efficiency of photovoltaic conversion of solar energy.
