摘要

双三相永磁同步电机模型预测电流控制以其概念直观、控制器参数少、易于处理、容错控制和非线性约束等优点成为研究热点。但由于电机参数不匹配,导致定子电流预测出现误差。为了解决这一问题,本文提出了一种带有预测误差校正的鲁棒预测电流控制(PEC-RPCC),该方法在定子电流预测方程中加入校正项。修正项由前一步定子电流预测值与采样值之差组成。仿真结果验证了该方法的有效性。

Robust Predictive Current Control of Dual Three-phase PMSM Using Prediction Error Correction
Model predictive current control of dual three-phase permanent magnet synchronous motor (PMSM) has become a research hotspot because of its intuitive concept, less controller parameters and easy to handle fault-tolerant control and nonlinear constraints. However, mismatched motor parameters lead to stator current prediction error. To solve this problem, a robust predictive current control with prediction error correction (PEC-RPCC) is proposed in this paper, where a correction term is added to stator current prediction equation. The correction term consists of the difference between the predicted value and the sampled value of the stator current in the previous step. Simulation results verify the effectiveness of the method.
