Abstract
This paper proposes a rapidcurrent response control strategyfor the six-step operation of permanent magnet synchronous motors(PMSM). This control strategy realizes dynamic over-modulation, flux weakening, and rapid current response without losing six-step steady operation. A flux weakening method for over-modulation which can effectively reduce the torque ripple in the over-modulation region is also proposed. Simulation results with a 64 kW prototype verify the effectiveness of this control strategy.
