带负载扰动前馈补偿的PMSM模型预测控制

本文提出了一种带负载扰动前馈补偿的永磁同步电机模型预测控制方法。根据永磁同步电机的基本方程和预测控制原理构建转速预测模型，采用一种改进的Luenberger观测器来估计负载转矩扰动，通过在转速预测控制器中引入负载扰动前馈补偿，来提高驱动系统的动态响应速度和抗负载扰动能力。实验结果表明，与传统的永磁同步电机模型预测转速控制相比，本文提出的控制方法在负载突变的情况下，转速波动更小，鲁棒性更强。

Model Predictive Control of PMSM with Load Disturbance Feed-forward Compensation

This paper proposes a model predictive control method with load disturbance feed-forward compensation for permanent magnet synchronous motor drives. Based on the equations of permanent magnet synchronous motors and predictive control principle, the speed predictive model is constructed. An improved Luenberger observer is used to estimate load torque disturbance, and the load disturbance feed-forward compensation is introduced in the speed loop to improve the dynamic response and anti-load disturbance ability. The experimental results show that, compared with the traditional speed model predictive control of permanent magnet synchronous motor, the proposed control method has smaller speed fluctuations and stronger robu stness when load torque changes.
