摘要

针对永磁辅助同步磁阻电机在电感饱和及参数失配工况下，传统无差拍预测电流控制易产生电流静差和脉动增大的问题，提出了一种电感饱和补偿下的自适应增量式无差拍预测电流控制方法。首先，通过相邻采样时刻预测方程相减建立增量式预测模型，削弱定子电阻和永磁体磁链偏差影响；然后，引入带电感饱和因子的自适应权重矩阵，将其与电流误差进行加权组合，实现对饱和效应引起的预测偏差的在线补偿；最后，采用电感与磁链分步辨识策略，将辨识结果实时反馈更新至参数自适应增量式无差拍控制器和最大转矩电流比控制器中。研究结果表明：所提方法可跟踪负载突变时的电感下降趋势，并能降低电流脉动；在10 N·m负载下，直、交轴电流脉动较增量式无差拍预测控制分别减小了0.06、0.40 A，较传统无差拍预测控制分别减小了0.08、0.50 A；磁链2倍失配时，负载突变后直轴电流静差降至0.01 A，A相电流总谐波畸变率为3.02%。该方法可为参数变化和饱和工况下的电机高性能控制提供参考。

Abstract

To address the issues of s

teady-state current error and increased current ripple in conventional deadbeat predictive current control (DPCC) for permanent magnet-assisted synchronous reluctance motors (PMA-SynRMs) under inductance saturation and parameter mismatch conditions

an adaptive incremental DPCC method with inductance saturation compensation is proposed.First

an incremental prediction model is established by subtracting the prediction equations of adjacent sampling instants

which mitigates the influence of deviations in stator resistance and permanent magnet flux linkage.Then

an adaptive weighting matrix incorporating an inductance saturation factor is introduced to weight the current error

achieving online compensation for prediction deviations caused by the saturation effect.Finally

a stepwise identification strategy for inductance and flux linkage is adopted

and the identified results are fed back in real time to update the parameter adaptive incremental deadbeat controller and the maximum torque per ampere controller.Experimental results show that the proposed method can track the decreasing trend of inductance during load transients and reduce current ripples.Under a 10 N·m load

the

-and

-axis current ripples are reduced by 0.06 and 0.40 A respectively compared to the incremental DPCC

and by 0.08 and 0.50 A respectively compared to the conventional DPCC.When the flux linkage is mismatched by a factor of two

the steady-state error of the

-axis current after a load transient decreases to 0.01 A

and the total harmonic distortion of the phase-A current is 3.02%.This method provides an effective reference for the high-performance control of PMA-SynRMs under parameter variations and inductance saturation conditions.
