| 摘 要： | 针对太阳能光伏发电系统中的最大功率点跟踪(MPPT)问题,提出了一种新的基于ARM控制的方案。系统采用基于玻尔兹曼函数的自适应控制算法搜索最大功率点(MPP),在外界环境相对稳定的情况下系统具有良好的稳定性,能稳定工作在MPP;当外部环境突变时系统能快速、准确地跟踪MPP。在硬件电路的基础上进行了实验,结果证明该系统可稳定快速地追踪MPP,具有较高的跟踪精度,并对光照突变等恶劣情况有较强的适应能力。

| Abstract: | A new scheme is proposed for the photovoltaic maximum power point tracking(MPPT) system which is based on ARM control.Adaptive algorithm based on Boltzmann function is used for searching maximum power point(MPP).In the stable and changeable environment,the system has good stability and can track photovoltaic MPP accuratly.The system performance is evaluated by experiments,and the results show that with the algorithm,the system can track the MPP smoothly and quickly and has good adaptability to problems like degradation of the photovoltaic illumination. |
