High-Performance Control of High-Speed Permanent Magnet Synchronous Motor Based on Least Squares Support Vector Machine Inverse System Method

摘要

This paper proposes a decoupling controlfor HS-PMSM based on the LS-SVM inverse system. In addition, the on-line LS-SVM inverse controller is developed for the pseudo-linear system. To achieve the high-accuracy stator flux estimation, a stator flux estimator is proposed and implemented for the HS-PMSM. A BPFC is designed to eliminate the magnitude and the phase errors. According to the comparative simulation and experiment results, the utility of the proposed control strategy is demonstrated by the improved decoupling control performance, the enhanced speed tracking performance, the strong load anti-perturbation performance, and the high-accuracy flux estimation at the wide speed range.
