基于双滑模观测器的PMSM模型预测转矩控制

This paper proposes a sensorless model predictive torque control (MPTC) method for PMSM using dual sliding mode observers. An EMF observer combined with an optimized orthogonal PLL estimates rotor speed, while a stator flux observer enhances prediction accuracy via feedback correction. Simulation and experimental results verify its effectiveness versus conventional position-sensor-based MPTC.

为了解决永磁同步电机中传统模型预测转矩控制算法依赖位置传感器的问题,提出1种基于双滑模观测器的模型预测转矩控制方法.首先,通过将反电动势滑模观测器与优化后的正交锁相环结合,用观测转速替换预测模型中的实时转速,实现无位置传感器控制.其次,应用定子磁链滑模观测器观测定子磁链,观测磁链通过反馈校正引入预测误差以获得更准确的预测转矩和磁链,提升模型的预测速度和精度.最后,通过MATLAB/Simulink仿真和实验平台与传统含位置传感器的模型预测转矩控制方法对比,验证所提方法的有效性和可行性.
