混合永磁轴向磁场磁通切换记忆电机分段弱磁控制
Flux-weakening Stage Control of Hybrid Permanent Magnet Axial Field Flux-switching Memory Machines
摘要
Abstract
Due to the usage of NdFeB and AlNiCo for hybrid excitations,hybrid permanent magnet axial field flux-switching memory machine (HPM-AFFSMM) exhibits the merits of high torque/power density as well as the online flux-adjustment characteristic.This paper proposed a novel wide speed range control strategy on the basis of the investigation of the flux-regulation principle,electromagnetic parameters and mathematical model of HPM-AFFSMM.Based on speed stage control,the PMs were fully magnetized in the low speed region,while the flux-weakening stage control algorithm was proposed in the high speed region,in which the required PM flux equaled the value corresponding to the maximal speed of one divided speed interval.In order to magnetize or demagnetize the PMs,an adaptive PM flux observer,which was insensitive to machine parameters,was presented over the whole speed range.Both the simulation and experimentation show that the control strategy proposed enables the machine to promptly accelerate the speed in the low speed region and optimize the flux control to extend the speed range in the high speed region.Therefore,the HPM-AFFSMM is very suitable for the integrated starter/generator (ISG) application.关键词
