Abstract

Abstract:

Noise is a big problem for switched reluctance motor. Aiming at the problem of large torque ripple in the operation of switched reluctance motor, the motor model obtained by finite element calculation was used to conduct the fuzzy PI direct instantaneous torque control of switched reluctance motor in MATLAB simulation. The Ansoft electromagnetic field simulation software was adopted to establish a three-phase 4/6 switched reluctance motor, and the obtained flux linkage data was introduced into the MATLAB motor model. Subsequently, a Simulink simulation experimental platform with a fuzzy PI direct instantaneous torque control was set up by the obtained model. Simulation results showed the system started to respond at 0.01 s and the torque was floating between 0.05~0.1 Nom. Therefore, the application of the motor model obtained by finite element to the simulation experiment of fuzzy PI direct instantaneous torque control could improve the system response and effectively suppressed the torque ripple.

Key words: switched reluctance motor, torque pulsation, finite element method, MATLAB, fuzzy PI, direct instantaneous torque, Ansoft
