Abstract:Due to the disadvantages of the conventional current control algorithm in dual-winding bearingless switched reluctance motor, such as the dependence on mathematical model, large torque ripple and complex control strategy, a novel control method is proposed in this paper to simplify the control algorithm, which is named direct instantaneous torque control (DITC) and direct force control (DFC). The method can greatly ease the control strategy by regulating the torque and levitation force independently and can reduce the torque ripple as well. Firstly, the hysteresis loop units of the inductance ascending and descending regions are given to realize DITC for BSRMs. After that, the switching states of power converter for levitation winding and the rules of its selection are introduced to achieve DFC. In addition, the system control block is also presented to facilitate the implementation of proposed control strategy. Finally, the simulation results are provided to verify the proposed control strategy. © 2019 IEEE.
