An off-line Optimization of Torque Sharing Functions for Switched Reluctance Motor Control

Abstract

This paper presents an optimization procedure to find optimal parameters of torque sharing functions (TSF) used in switched reluctance motor control. A finite element method simulation model of the motor is built and verified to evaluate the objective function. The result of the optimization is a set of functions that calculate optimal values of start angle and overlap angle of sinusoidal TSF for every operational point of the motor. Using different objective functions, including efficiency and a torque ripple, leads to the different start angle and overlap angle functions.
