混合励磁轴向磁场磁通切换永磁(hybrid excited axial field flux-switching permanent magnet,HEAFFSPM)电机是一种新型定子励磁型混合励磁同步电机,它结合了轴向磁场磁通切换永磁电机和电励磁同步电机的优点.为了研究该结构电机在全速度运行范围内的运行性能,论文详细分析了电机结构特征与调磁机理,构建了电机数学模型和矢量控制系统.基于分区控制策略,在低速区,为了提高电机驱动系统的功率因数,提出一种单位功率因数控制策略,且与id=0控制进行对比研究;在高速区,为拓宽电机调速范围,提出一种最大输出功率弱磁控制策略,且与传统弱磁控制策略进行对比研究.基于MATLAB/Simulink和dSPACE 1103,采用提出的控制策略对电机全速度范围的运行性能进行研究.仿真与实验结果表明,在低速区,电机轻载或重载运行时,单位功率因数控制策略始终保持电机驱动系统运行功率因数为1,使逆变器容量得到了充分利用;在高速区,最大输出功率弱磁控制策略提高了电机弱磁运行区域的功率利用率,增强了电机带载能力,拓宽了电机调速范围,提高了弱磁运行区的效率.“,”The hybrid excited axial field flux-switching permanent magnet (HEAFFSPM) machine is a novel stator-excitation hybrid excited synchronous machine,which combines the advantages of the axial field flux-switching permanent magnet machine and the electrically excited synchronous machine.In order to study the operating performances of the HEAFFSPM machine in whole speed operation regions,the structure and adjustment principle of magnetic fields of the machine were analyzed.The mathematical model of the HEAFFSPM machine was deduced and the vector control system was established.To increase the power factor of machine drive system,a kind of unit power factor control strategy was presented in the low speed region,and compared to the id=0 control.To broaden the speed-regulation range of the HEAFFSPM machine,a kind of maximum output power flux-weakening control strategy was proposed in the high speed region,and compared the traditional flux-weakening strategy.Based on the MATLAB/Simulink and dSPACE1103,the simulation analysis and experiment research for verifying the operating performance of the HEAFFSPM machine was implemented by using the proposed control strategy.The results demonstrate that the unit power factor for the drive system can be achieved at different speed and load while the inverter capacity is utilized completed in the low speed region.The speedregulation range is broaden while the efficiency is increased in the high speed region.Finally,the load capacity of the HEAFFSPM machine is enhanced.
