摘　　要：传统的太阳跟踪方式多采用光电跟踪或视日运动轨迹跟踪控制方式,存在着跟踪精度低、有累积误差等缺点。为了改进对太阳的跟踪精度和消除累积误差,提高太阳能的利用率,设计了一种基于Atmega16单片机为控制核心的跟踪控制系统,采用光电跟踪和视日运动轨迹跟踪互补的控制方式。在跟踪策略上,晴天采用光电跟踪,阴天采用视日运动轨迹跟踪,实现了全方位、高精度、全天候的实时精准跟踪。试验结果表明,该控制系统工作性能稳定,实现了实时精确的太阳跟踪。Traditional way of the sun tracking control usually separately takes the way of photoelectric tracking or sun angle tracking control system,but it always has lower tracking precision,large cumulative errors and other shortcomings.In order to improve the accuracy of tracking the sun,eliminate accumulation error and improve the utilization of solar energy,a solar tracking control system was designed based on Atmega16.Atmega16 is the core in control system,used photoelectric tracking and sun angle tracking complementary control mode.The photoelectric tracking strategy is used at sunny days,sun angle tracking is used while cloudy day,the all-round,high-precision,all-weather real-time accurate tracking was realized.The result shows that the tracking control system can work steadily and realize the real-time tracking precision of the sun.
