摘要
基于先进Cortex-M3内核的微处理器STM32,结合双电机驱动器与高精度光敏传感器,研究并设计了一套高精度太阳能跟踪系统。该系统以实时时间为基准精确追踪太阳位置,以光敏传感器进行误差修正,利用STM32优越的PWM方式控制电机,实现太阳能接受效率的最大化。实验结果表明,系统工作稳定可靠,基本实现了对太阳的实时跟踪。
Combining two motor drives with four high precision photosensitive sensors, a type of sun auto-tracking system is designed based on Cortex-M3 kernel of the microprocessor STM32. The system accurately tracks the position of the sun based on real-time,using photosensitive sensors for error correction. In order to get the maximum efficiency of solar energy, the internal superior PWM controller of STM32 is adopted to control motors. The experimental results show that the system can work steadily and reliably ,with high accuracy tracking the sum basically.
