中文摘要：
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TSM320F2812DSP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。
英文摘要：
Solar LED lighting system as the new lighting technology has many advantages, such as green power usage, comfortable feeling and high efficiency. However, the complex and high performance control requirements challenged the control system, such as maximum power point tracking （MPPT） control, LED nonlinear load control and battery charging strategy selection. In this paper, the control system demands are analyzed. The MPPT control, battery charging strategy and LED load control research are achieved and simulations based on MATLAB/Simulink are accomplished. By using the simulation modules and eZdsp embedded target modules, the programs are genera- ted for TMS320F2812 DSP＇s control. High performance experiments are also achieved for the LED lighting system, such as fast dynamic response, smooth starting current and high precision for steady-state. This paper also sets up an ideal control module of LED lighting system. The experimental programs generation based eZdsp provides an efficient realization for the DSP control system.
