Predictive Current Control of Switched Reluctance Machine for Accurate Current Tracking to Enhance Torque Performance

This paper proposes a predictive control technique for accurate tracking of the current reference in a switched reluctance motor drive. The fast dynamic response of the proposed current control technique is demonstrated through tracking of square current and optimal current wave-shapes over a wide ranges of torque and speed through simulation and experiments. Accurate tracking of different current wave-shapes are required to obtain desired average torque, as well as to minimize torque ripple and losses. Proposed technique offers improved performance over existing state-of-the-art techniques such as gain-scheduling and delta modulation. Experimental results show consequent fast torque response and low torque ripple.
