Robust Direct Speed Predictive Control Method for Rare-Earth Permanent Magnet Motor
摘要
Abstract
A robust direct speed prediction control method based on an extended state observer is proposed to address the issue of poor speed performance in the direct speed control of rare-earth permanent magnet synchronous motors due to unmodeled disturbances.The local mathematical model of the rare-earth permanent magnet synchronous motors is derived,and multiple extended state observers are designed to observe the unmodeled disturbances and parameter variations in the system,thereby improving the robustness of the con-troller and the response speed to load disturbances.Finally,the effectiveness of the proposed control strategy is verified by constructing a drive system based on a rare-earth surface-mounted permanent magnet synchronous motor.关键词
