Background: In this paper, experimentation fault-tolerant control for permanent magnet
synchronous motor drive system using the direct torque control technique is presented.
Methods: Synchronous machine drive system requires uninterrupted and more secure conditions during
Results: Therefore the diagnostic of voltage source inverter and synchronous motor faults are needed
for improving system availability.
Conclusion: This article aims to propose an accurate open-phase fault detection and fault-tolerant
inverter of a permanent magnet synchronous motor using direct torque control technique. Experimental
implementation is carried out on powerful dSpace DS1104. The validity of the proposed method has
been experimentally verified.
