Abstract

This paper deals with a new method PMSM driver inverter faults detection and isolation based on EKF (Extended Kalman Filter). Firstly, a nonlinear model of PMSM diver where the on resistance of inverter FET is included as state variable is derived. Secondly, the method to detect and isolate inverter fault from the estimated on resistance is presented. Finally, the usefulness of the proposed scheme is verified by simulation results.
基于ekf的PMSM驱动逆变器故障检测与隔离
提出了一种基于扩展卡尔曼滤波的永磁同步电机驱动逆变器故障检测与隔离的新方法。首先,建立了以逆变场效应管导通电阻为状态变量的永磁同步电机非线性模型。其次,提出了从估计电阻中检测和隔离逆变器故障的方法。最后,通过仿真结果验证了所提方案的有效性。
