摘　　要：目的目前六相永磁同步电机单相开路故障的模型预测容错控制的研究已逐步成为热点,本文将对α-β和d-q2种坐标系控制下的故障机理进行对比分析,并对比不同坐标系中下正常和故障容错运行模型的控制效果。方法基于矢量空间解耦坐标变换矩阵不变原理,对A相开路进行故障模型的理论计算分析,分别在α-β和d-q这2种不同坐标系中对其进行模型预测控制容错建模。最后在MATLAB/Simulink中对2种坐标系下的电机正常运行和故障容错运行中的工作性能采用相同电机参数进行实时仿真。结果仿真结果显示,正常运行时,2种坐标系下总谐波失真(THD)值分别为2.09%和2.77%;故障运行时,d-q坐标系下的THD值比α-β坐标系小了13.15%;容错运行时2种坐标系下的THD值分别为1.19%和1.79%。结论从仿真结果可以看出,d-q坐标系控制下的电机在故障时具有更稳定的性能,而在正常和容错运行状态下,2种坐标系下的控制效果几乎等效。At present,the model predictive fault-tolerant control of single-phase open fault of six-phase permanent magnet synchronous motor has gradually become a hot topic.The work aims to comparatively analyze the fault mechanism underα-βand d-q coordinate system control and compare the control effect of normal and fault-tolerant operating models in different coordinate systems.Based on the vector space decoupling coordinate transformation matrix invariant principle,the A-phase open fault model was theoretically calculated and analyzed,and the model predictive control fault-tolerant modeling was carried out in two different coordinate systems,α-βand d-q respectively.Finally,in MATLAB/Simulink,the same motor parameters were used for real-time simulation of the normal operation and fault-tolerant operation of the motor in the two coordinate systems.The simulation results showed that under normal operation,the THD was 2.09%and 2.77%respectively.In fault operation,the THD inα-βcoordinate system was 13.15%smaller than that in d-q coordinate system.In fault-tolerant operation,THD was 1.19%and 1.79%respectively in the two coordinate systems.It can be seen from the simulation results that the motor controlled by d-q coordinate system has more stable performance when fault occurs,and the control effect under normal and fault-tolerant operation conditions is almost equivalent.
