doi:10.16182/j.issn1004731x.joss.201803038

Abstract

Abstract: In order to smoothly switch different control modes of switched reluctance motor under the condition of low speed and high speed, a novel scheme using function fitting method to control turn-on angle, turn-off angle and phase current chopping is proposed. The active disturbance rejection speed control system is structured for switched reluctance motor in order to restrain all kinds of disturbance and improve the dynamic performance. Simulation results indicate that the principle of the method is correct and the turn-on angle, turn-off angle and phase current chopping is coordinated to realize the smooth switching of different control modes with low speed and high speed. The dynamic performance of the system operates well.

Key words: switched reluctance motor, active disturbance rejection control, entire speed range, function fitting method, smooth transition
