Experimental Implementation

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 operations. 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.

In order to deeply understand the characteristics of the permanent magnet synchronous motor direct torque control method, its mathematical models were established in the two-phase stationary coordinate system, the two-phase synchronous rotating coordinate system, and x-y stator synchronous rotating coordinate system. The implementation process of direct torque control method in varied stator winding connection was analyzed in detail. In order to improve the speed and torque performance of the permanent magnet synchronous motor, the direct torque control block diagram and the space voltage vector selection table were given. Finally, the summary and outlook of reducing torque ripple in the permanent magnet synchronous motor direct torque control methods.
