模组式双三相永磁电机两相开路低振动容错策略
Two-phase Open-circuit Low Vibration Fault-tolerant Strategy for Modular Dual Three-phase Permanent Magnet Motors
摘要
Abstract
The torque and vibration performance of the modular dual three-phase permanent magnet servo motors(MDTP-PMSMs)significantly deteriorate under the two-phase open-circuit fault-tolerant condition.This is not conducive to the high-quality fault-tolerant operation of the permanent magnet servo motor system.In this paper,a low vibration fault-tolerant strategy is proposed.The torque and vibration performances in MDTP-PMSMs under the two-phase open-circuit condition are improved.First,according to the winding configuration of the MDTP-PMSM,the torque ripple and radial force characteristics of the existing fault-tolerant strategy are analyzed by using the MMF vector superposition method.Subsequently,the multi-objective low vibration reconfiguration model is established.The restraints and the MMF harmonic optimization goals are clarified.The optimal fault-tolerant current expression is achieved by the multi-objective differential evolution algorithm.Furthermore,the torque and radial force before and after the proposed fault-tolerant strategy are compared.The effectiveness of the proposed fault-tolerant strategy is validated.Finally,the experimental results show that the torque ripple and vibration can be reduced evidently by the proposed method under the two-phase open-circuit fault condition for the MDTP-PMSM.关键词
