基于MPCC的永磁同步电机驱动系统逆变器IGBT开路故障诊断方法
MPCC-based Open-circuit Fault Diagnosis Method for the Inverter IGBT of PMSM Drive System
摘要
Abstract
To address the problem of the long detection time of the current detection method during the open circuit fault diagnosis of inverter insulated gate bipolar transistor(IGBT)of the permanent magnet synchronous motor(PMSM)drive system,an error current polarity method based on model predictive current control(MPCC)was investigated.By combining the variation of the cost function in MPCC with the current detection method,the fault detection time can be effectively reduced.However,the MPCC is susceptible to changes in motor parameters,the load torque and speed changes may lead to changes or mismatches in the motor parameters,which in turn affect the output of the cost function and lead to misdiagnosis.To address the issue,the fault detection indicators were normalized and a counting method was added to the MPCC-based error current polarity method to further improve the robustness of fault diagnosis.关键词
