基于电压残差的双三相永磁同步电机开路故障定位及容错控制补偿策略
Fault Location and Fault-tolerant Control Compensation Strategy for Dual Three-phase PMSM With Open Circuit Fault Based on Voltage Residual
摘要
Abstract
Fault-tolerant operation can be realized by adjusting the current amplitude and phase after a winding open-circuit fault occurs in a motor,but the influence of the voltage residual on fault-tolerant operation is not considered.This paper proposes a fault location and fault-tolerant control compensation method based on the voltage residual for open circuit faults in dual three-phase motors.Firstly,the faulty phase is located based on the characteristics of the y-axis voltage residuals corresponding to the faulty phase and the healthy phase.Subsequently,the post-fault voltage vector offset is analyzed,and a global voltage vector compensation strategy is proposed in combination with a fault-tolerant method based on current control to further reduce the torque pulsation in fault-tolerant operation.In particular,for the process between the occurrence of a motor fault and the switch-over to the fault-tolerant algorithm,the residual-based voltage compensation method is utilized to suppress the torque fluctuation under faulty motor operation.Finally,experimental results demonstrate that the proposed method can accurately locate open-circuit faults,ensure smooth operation during the transition phase through voltage compensation,and further reduce the torque pulsations of fault-tolerant operation.关键词
