Abstract: 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.
Key words: Atmega16; photoelectric tracking; sun angle tracking
