The design of closed-loop control system of solar automatical tracking

The low power MCU(STC12C5A60S2) of Hongjing Technology Company is the control core of the system the, which through the signal detection module, attitude measurement module and motor drive module to realize the closed-loop control of automatic tracking the sun. The paper introduces the overall design ideas and the technical details of each part of the design, using the strategy and raising the control strategy of date which is proposed trajectory tracking coarse and fine-tune the optical signal tracking to ensure the tracking control accuracy. The reliability and anti-jamming of the system is increased remarkably with this tracking algorithms.
