인휠모터 구동 차량의 모터 고장 검출 및 진단

This paper presents a fault detection algorithm for the in-wheel motor drive vehicle by estimating the internal resistance of the motor. The proposed fault detection algorithm is developed based on the least square identification method using the input and the output data. The nonlinear permanent magnet synchronous motor (PMSM) model and a PMSM control algorithm are developed to simulate the fault detection algorithm. The simulation results show the validity of the proposed fault detection algorithm.
