Research on the switched reluctance motor drive system

The structure of switched reluctance motor for the hybrid vehicles is shown firstly in this paper. Basing on the mechanical characteristics and the electrical characteristics, in order to optimize the drive system efficiency, reduce the noise and torque ripple, upgrade the capability of output, three different control strategies are proposed in the paper. Current chopping control, voltage chopping control and the angle position control are designed to the low, medium, high speed respectively. The whole integrated strategies and the detailed independent control algorithms are represented in the following chapters. The switched reluctance motor drive system is established to verify the correctness of the control strategies, the software program and the hardware design. The experiment results directly confirm their suitable and the flexible behaviors.
