Abstract

This study presents a method to reduce the chattering phenomenon and the reaching time of sliding mode speed control for switched reluctance motors (SRMs). In order to simultaneously reduce the chattering phenomenon and reaching time, we propose a hybrid reaching law (HRL) for sliding mode controller (SMC). Furthermore, to address the absence of a position sensor, a sliding mode observer (SMO) is integrated into the proposed HRL-based SMC, enabling accurate estimation of rotor angle and angular speed. Comprehensive simulation results are conducted to verify the effectiveness of the proposed method in terms of the reduced chattering phenomenon and reaching time.
Keywords: chattering phenomenon; electric motors; position and speed estimation; sliding mode control; switched reluctance motors chattering phenomenon; electric motors; position and speed estimation; sliding mode control; switched reluctance motors
