摘要
This study deals with the comparison of the dynamic modelling, the transient and steady-state performances analysis and experimental verification for a 12/8 dual-channel switched reluctance machine (DCSRM) under single-and dual-channel operation modes. The DCSRM has inherent short flux paths capability, and the magnetic circuits for both the channels share most of the magnetic real estate in the machine under dual-channel excitation mode. According to the different flux patterns, the dynamic models for the DCSRM operating under different modes are presented. In this proposed dual-channel operation model, the mutual coupling between different phases in each channel of the DCSRM is considered. By using the dynamic models, various transient and steady-state performances such as starting up speed under closed-loop control, phase currents, phase flux linkages, total torque characteristics and sudden change in torque operation are predicted and compared for the DCSRM under different modes and excitation conditions. It is shown that when the DCSRM operation is under dual-channel mode, it has faster acceleration performance and the torque is more than two times of that under single-channel mode. Finally, an experimental laboratory set-up based on digital signal processor and complex programmable logic device (CPLD) is built, which verify the proposed modelling and analysis. The experimental results of transient and steady-state performances are compared with the simulation results in the DCSRM systems under single-and dual-channel operation modes.
