| 摘 要： | 太阳能LED照明系统作为新型照明方式,不仅具有独立光伏照明系统的诸多优点,如清洁无污染、无需长距离输电导线等,还具有LED照明的发光效率高、光线柔和、光伏电池设计容量小等诸多优势。但系统需实现最大功率点跟踪(MPPT)控制、LED非线性负载放电控制和蓄电池充放电控制等功能,对控制具有较高要求。本文对控制系统要求进行分析,分别进行了MPPT、充电策略和LED放电控制的研究,并采用MATLAB/Simulink对主电路和控制系统进行仿真。基于仿真模型,采用嵌入式目标模块eZdsp生成TSM320F2812 DSP控制程序,对仿真模型进行快速转化,并在硬件平台对具体控制系统进行实现。系统具有动态响应快、启动电流平滑、稳态精度高等优点,从而得出适合太阳能LED照明系统的控制方法。
