Abstract
En 中文
This paper presents an enhanced control strategy for torque ripple mitigation in switched reluctance motors (SRMs) by combining a torque online correction (TOC) method with a composite speed controller. The proposed TOC dynamically allocates the reference torque using an optimized torque sharing function (TSF), predicts torque boundaries based on real-time phase currents, and applies online correction through lookup tables to ensure precise tracking between actual and reference phase torques. To further improve dynamic performance, a composite speed controller integrating an extended sliding mode disturbance observer (ESMDO) and adaptive sliding mode control (ASMC) is developed. The ASMC incor-porates an innovative reaching law to suppress chattering and accelerate convergence, while the ESMDO provides robust disturbance estimation for internal and external uncertainties. Experimental results demonstrate that the proposed method significantly reduces torque ripple, enhances speed response, and improves overall system robustness against disturbances. The integrated approach achieves superior performance compared to conventional control methods while maintaining practical feasibility for implementation
