摘要

摘要: 由于混合永磁记忆电机(HPMMM)永磁体在线充磁与去磁时转子磁链定向难度大, 针对HPMMM永磁体在线调磁时磁链观测精度不高的问题, 提出了一种基于全阶状态滑模观测器的混合磁链观测方法。该方法采用全阶磁链观测器并结合滑模反馈部分保证电流观测值收敛于真实值, 同时对HPMMM定子电流与转子磁链实时观测，进而获得更高精度的转子磁链观测。全阶状态滑膜观测器应用于HPMMM矢量控制策略中, 优化了系统整体控制复杂程度。最后通过仿真对比分析, 相比传统永磁同步电机而言, HPMMM调速范围更宽, 交直轴电流波动较小, 收敛于实际磁链速度更快, 表明该方法能进一步提高交流脉冲对HPMMM充磁和去磁时磁场定向的准确性, 增加系统参数鲁棒性、稳定性。

Abstract: To improve the accuracy of flux linkage observation in on-line tuning of the hybrid permanent magnet memory machine(HPMMM), a hybrid flux linkage observation method of full-order state sliding mode observer is proposed. This method combines a full-order flux linkage observer with the feedback part of the sliding mode to ensure that the current observation converges to the true value. The HPMMM stator current and rotor flux linkage are observed in real time, and the rotor flux linkage observation is obtained with higher precision. The full-order sliding mode observer is applied to the vector control strategy of HPMMM for optimizing the overall control complexity of the system. Simulation shows that, compared with the traditional permanent magnet synchronous motor(PMSM), HPMMM has a wider speed range, smaller direct-axis and quadrature-axis current fluctuation, and faster speed of convergence to actual flux linkage, indicating that the proposed method can further improve the accuracy of the magnetic field orientation by AC pulse during magnetization and demagnetization of HPMMM and enhance the robustness and stability of the system parameters.
