This paper proposes a speed sensorless control for PMSM motor drive system. The sensorless strategy is based on back-emf estimation of the motor, suited for applications at high speed. The drive system uses a four-switches three-phase inverter. This topology is attractive specially in fault condi...
This paper describes analytical and simulation tools to analyze the effects of Open Switch Fault (OSF) and Open Phase Fault (OPF) on five-phase PMSM designed for aerospace applications. For such applications, the fault tolerance and the reliability of the drive (PMSM and the power converter) ar...
Based on a three-phase four-switch inverter,we propose a model of predictive current control( MPCC)strategy for permanent magnet synchronous motor( PMSM) drive systems with a model reference adaptive system( MRAS) observer. Because stator resistance varies with temperature change,we design an MRAS ...

In this article, an optimized fault-tolerant control (FTC) method without current judgement is proposed for open-switch faults (OSFs) in dual three-phase permanent magnet synchronous motor (DTPMSM) drives. The reason for the torque ripple under OSFs has been investigated. The theoretical analysis...
