| 摘 要： | 分析了光伏电池的输出特性.根据光伏电池的功率-电压曲线,在已有控制算法的基础上,采用灰色模糊/PID双模控制,即在外界环境或者负载发生变化,导致远离最大功率点时,采用模糊控制进行控制,使系统能够快速跟踪到最大功率点.由于模糊控制属于有差控制,在最大功率点附近仍然有震荡,造成一部分功率损失,所以当系统工作在最大功率点的附...

| Abstract: | The output characteristics of photovoltaic cells are analyzed.According to power-voltage curve of photovoltaic array,on the basis of the existing control algorithm,the gray fuzzy / PID dual-mode control is adopted;that is to say,when it far from the maximum power point because of the changes of external environment or the loads,the fuzzy control is used to track maximum power point(MPP) quickly.For the fuzzy control is the error-control,the fluctuation nearby the MPP is still exist,so when it is nearby MPP,... |
