最小化传感器使用的三相永磁同步电机驱动控制

This article investigates the control of three-phase permanent magnet synchronous motor (PMSM) drives with minimum sensor usage. To minimize the number of required current sensors, the dual space vector modulations (SVMs) are proposed for phase current reconstruction, synchronously executing vector synthesis twice within a control period. Furthermore, combining the extended Kalman filter and the m...
