This study proposes a photovoltaic tracking control system architecture with a single - chip microcontroller (MCU). Its core consists of a multimodal sensing unit, self - adaptive control module, and energy optimization management unit. The system’s five - degree - of - freedom modular design includes key structures like a multi - channel light intensity detection module, dynamic compensation control module, intelligent information processing unit, high - precision actuator, and human - machine interaction interface. A fourth - order state - space model with a Kalman filter is established to depict system dynamics and suppress disturbances. By integrating a state observer with a self - adaptive control strategy, the system maintains stable tracking (overshoot < 4.2%) under sudden illuminance changes (>20% irradiance change/min). Field tests show the design increases daily energy capture of the PV array by 37.6% (vs. fixed installations) while cutting drive unit energy consumption by 42.3%.

摘要

This study proposes a photovoltaic tracking control system architecture with a single - chip microcontroller (MCU). Its core consists of a multimodal sensing unit, self - adaptive control module, and energy optimization management unit. The system’s five - degree - of - freedom modular design includes key structures like a multi - channel light intensity detection module, dynamic compensation control module, intelligent information processing unit, high - precision actuator, and human - machine interaction interface. A fourth - order state - space model with a Kalman filter is established to depict system dynamics and suppress disturbances. By integrating a state observer with a self - adaptive control strategy, the system maintains stable tracking (overshoot < 4.2%) under sudden illuminance changes (>20% irradiance change/min). Field tests show the design increases daily energy capture of the PV array by 37.6% (vs. fixed installations) while cutting drive unit energy consumption by 42.3%.
