摘要：
The application of permanent magnet synchronous motor (PMSM) is becoming more and more popular. The reliability of PMSM has become a research hotspot. The fault diagnosis method of current sensor for PMSM drive system is studied in this paper. The fault type of the current sensor is analyzed and the fault model is built. Using the method of changing the stationary coordinate frame, the current reference value is compared with the sampled value from the sensor. Then the fault diagnosis method based on the residual error is used to diagnose the fault of the current sensor. Experimental results show that the proposed method could realize the fast and accurate positioning of the fault phase current sensor.
