Fault Diagnosis of PMSM Drives Based on Digital Twin Modeling

To realize accurate fault diagnosis of electrical faults for the permanent magnet synchronous motor (PMSM) drive, a digital twin modeling assisted fault diagnosis method is proposed in this article. By developing a digital twin system for physical PMSM drives, the states of physical PMSM drives are precisely monitored and fault classification can be achieved without misdiagnosis. Simulation results are given to validate the feasibility of the proposed method.
