【摘要】：混合永磁轴向磁场磁通切换记忆电机(hybrid permanent magnet axial field flux-switching memory machine,HPM-AFFSMM)采用钕铁硼和铝镍钴两种永磁励磁,既具有轴向磁通切换永磁同步电机转矩和功率密度高的优点,又具有记忆电机永磁磁化状态在线可调的特点。在研究HPM-AFFSMM调磁原理、电磁参数及数学模型的基础上,提出了一种HPM-AFFSMM宽调速控制方法。基于分区控制,低速区采用永磁饱和磁化方式运行,高速区采用分段弱磁方式运行。在分段弱磁区域,所需永磁磁链满足给定转速所在区间内的最大转速对应的永磁磁链。在全速度范围内,为实现充去磁,提出了一种对电机参数敏感性较低的自适应永磁磁链观测器设计方法。仿真和实验结果表明,在低速区,饱和增磁运行缩短了电机的起动过程;在高速区,分段弱磁运行优化了永磁磁链的控制,拓宽了电机的调速范围。因此,HPM-AFFSMM非常适合应用于电动汽车起/发一体机。
[Abstract]:The hybrid permanent magnetic axis magnetic flux switching memory motor (hybrid permanent magnet axial field flux-switching memory machine, HPM-AFFSMM) uses two kinds of permanent magnets, NdFeB and Al NCO, not only with the high torque and power density of the axial flux switching permanent magnet synchronous motor, but also the permanent magnetic magnetization of the memory motor. On the basis of studying the principle of magnetic flux modulation, electromagnetic parameters and mathematical model of HPM-AFFSMM, a kind of HPM-AFFSMM wide speed control method is proposed. Based on the zoning control, the low speed region runs with permanent magnetic saturation magnetization, and the high speed area operates by subsection weak magnetic mode. In the segmented weak magnetic region, the permanent magnetic chain is required to meet the given speed. In the full speed range, an adaptive permanent magnetic flux observer design method with low sensitivity to the motor parameters is proposed. The simulation and experimental results show that the starting process of the motor is shortened in the low speed zone, and the segmented weak magnetic transport in the high speed area. It optimizes the control of permanent magnet flux and widens the speed range of motor. Therefore, HPM-AFFSMM is very suitable for electric vehicle starting / delivering machine.
