基于新型多电平功率变换器的SRM转矩分配函数控制方法
Torque sharing function control method of SRM based on novel multilevel converter
摘要
Abstract
Due to the limitation of the switched reluctance motor(SRM)bus voltage and the unreasonable torque distribu-tion of the conventional torque sharing function(TSF)control,the torque ripple in the overlap conduction region is not sufficiently suppressed,and the torque ripple increases further as the speed rises.In order to improve this problem,a SRM online TSF control method based on a novel multilevel converter(MLC)is proposed.This method takes advantage of the high-voltage fast excitation and high-voltage fast demagnetization capabilities of the novel MLC to improve the torque following capacity of each phase winding.The overlap conduction region is divided into two regions,and the reference torque is distributed online in different regions according to the torque output capability of each phase to further reduce the torque following error.At the same time as reducing the torque ripple,in order to further reduce the copper loss of the motor,a particle swarm optimization(PSO)algo-rithm is used to optimize the angle control parameters offline under different operating conditions.Simulation and experimental verify that the proposed method effectively reduces motor torque ripple,especially at high speeds,with a maximum reduction of 46.6％compared to traditional methods.At the same time,motor efficiency has also been improved.关键词
