Multimode Drive and Control for Double-Stator Switched Reluctance Motor by a Three-Switch Symmetrical Converter

In this article, a multimode drive and control scheme is proposed to enhance the operation performance of double-stator switched reluctance motor (DSSRM) based on a new three-switch symmetrical converter (TSSC). First, the topology and feasible six operation modes of DSSRM are analyzed. Second, the topology of the proposed TSSC is presented to develop the multimode drive of DSSRM with two connection methods. Meanwhile, the working mode analyses are carried out in single-phase operation, two-phase serial operation, and two-phase parallel operation. Moreover, the fault tolerance of TSSC is also explored based on its redundant excitation channels. Next, a control method is designed to lower the phase-to-phase interference and enhance the dynamic performance based on the switching angle selection and linear active disturbance rejection control. Finally, the simulation and experiment are carried out, demonstrating that the proposed drive and control strategy can meet the multimode operation requirements of DSSRM to reduce the cost, improve the fault tolerance, and enhance the dynamic performance.
