Experimental fault-tolerant control of a PMSM drive

Abstract

The paper describes the study and experimental verification of remedial strategies against failures occurring in the inverter power devices of a PM synchronous motor drive

Analysis of Vertical Strip Wound Fault-Tolerant Permanent Magnet Synchronous Machines

“…This is partly due to the machine needing to overcome the breaking torque produced by the faulty unit and partly due to the decreasing torque constant with current due to saturation. Such a machine needs to be designed to handle the additional current loading in accordance with the post-fault operating requirements [18,36]. Fig.8a and b Fig.8c shows the temperature excursion in the shorted turn during the three operating conditions, i.e.…”

Fault Tolerant Three-Phase AC Motor Drive Topologies: A Comparison of Features, Cost, and Limitations

“…A fault redundant topology for permanent magnet motors was presented in [15]. This topology will be referred to as the double switch-redundant topology and is shown in Fig.…”

“…10. The configuration [15] will be referred to as the phase-redundant topology. This circuit topology incorporates the fault isolating SCRs and fuses in only the three active legs of the inverter.…”

“…1) to create systems that are tolerant to one or more types of faults. Papers that report fault tolerant systems include [6], [12]- [15], and [18]- [21]. These papers all rightfully claim to provide fault-tolerant capabilities under the conditions specified.…”

Etude comparative de différents correcteurs pour la commande optimale avec défauts d’une machine pentaphasée

“…Ces méthodes sont basées sur la modification de la forme d'onde du courant d'une ou plusieurs phases actives de la machine. Pour une structure classique triphasée composée d'un onduleur à q bras, certains auteurs proposent d'ajouter un bras supplémentaire pour contrôler le courant homopolaire (Bolognani et al 2000). Pour une structure d'alimentation ou chaque phase est associée à un onduleur monophasé, certains auteurs proposent également de modifier l'amplitude des courants dans les phases actives (Martin et al 2000)- (Martin et al 2007).…”
