Switched Reluctance Machine: A Possible Propulsion Solution in Electric, Hybrid Electric and Plug-in Hybrid Electric Vehicles

Speaker: Jin Ye

Time: May 24, 4:30pm - 6:00pm.

Location: Room 405, Administration Center

Abstract:

This talk will mainly focus on challenges and enabling solutions of electric motor drives in electric vehicles (EVs), hybrid electric vehicles (HEVs) and Plug-in hybrid electric vehicles (PHEVs). Switched reluctance machine has recently emerged as a possible cost-effective propulsion solution in EVs, HEVs and PHEVs due to its simple and rugged structure, its extended-speed constant-power range, fault-tolerant capabilities and lack of permanent magnets in its configuration. However, it suffers from high torque ripples and high acoustic noise due to strong nonlinearity of the machine, which impedes its penetration to electrified transportation. In this talk, two novel control methods for torque ripple reduction in switched reluctance machine will be discussed, both of which are validated to reduce the torque ripples significantly over the wide speed range in both linear magnetic and saturated magnetic region. In addition, the effect of mutual flux on rotor position estimation of switched reluctance machine is investigated and two methods will be introduced to eliminate the mutual flux effect on rotor position estimation of witched reluctance machines without a prior knowledge of the mutual flux profiles.
