In order to realize air-gap flux on-line adjustment of permanent magnet machine, researchers proposes a variety of new variable flux memory machine (VFMM). This paper proposes a sliding mode (SM) based direct torque control (DTC) strategy for VFMM. The normal operation utilizes a DTC incorporating id = 0 condition method while reference stator flux linkage pulses are energized in MS manipulation regions. This avoids continuous magnetizing current and complicated decupling algorithm. Compared with vector control, the proposed DTC method has more simple structure with better dynamic performance and exhibits less dependence on topology parameters. Finally, the effectiveness of the proposed control scheme is validated by simulation results.
