摘　　要：针对目前电机轻载运行效率低和起动电流过大所引起的能量损耗问题,提出了基于最小电流的模糊控制方法.以电流和电流的变化为输入量,通过模糊控制得到晶闸管的触发角,限制起动电流达到节能目的.实验结果表明,起动电流限制在一定范围内,达到了节能目的.For solving the energy wastage caused by low efficiency in small power and the overlarge starting current,a fuzzy control method based on the minimum current is presented. The trigger angle of thyristor is obtained through fuzzy control while the current and the error of current are taken as input variables,and then the energy saving is realized by limiting the starting current. Experimental result indicates that the starting current is limited and the energy saving can be obtained.
