摘　　要：高性能永磁电机系统已成为硬质合金生产成型装备的关键与核心部件,电机系统参数失配将严重影响合金产品成型装备综合效率。为了优化模型参数失配和一拍延迟对永磁同步电机(PMSM)电流控制性能的影响,提出一种具有参数在线矫正的鲁棒无差拍预测电流控制(POC-DPCC)方法。首先,对常规无差拍预测电流控制的参数敏感性进行分析;然后,设计基于Adaline神经网络的多参数误差在线辨识器,并提出一种以参数失配误差为神经网络权值的新型辨识结构来提升参数变化跟踪性能;最后,提出POC-DPCC方法,通过更新控制电压系数矩阵来提高系统对电机参数的鲁棒性,以下一时刻电流预测值代替当前时刻采样电流来补偿一拍延迟的影响。对比仿真和实验结果,可以验证所提方法在复杂工况下的有效性和鲁棒性。The high-performance permanent magnet motor system has become a key and core component of hard alloy production molding equipment.The mismatch of motor system parameters will seriously affect the overall efficiency of alloy product molding equipment.In order to mitigate the effects of model parameter mismatch and one beat delay on the current control performance of permanent magnet synchronous motor(PMSM),a robust deadbeat predictive current control(POC-DPCC)method with online parameter correction is proposed.Firstly,the parameter sensitivity of conventional deadbeat predictive current control is analyzed.Then,a multi-parameter error online identifier based on Adaline neural network is designed,and a new identification structure with parameter mismatch error as the neural network weight is proposed to improve the tracking performance of parameter changes.Finally,the POC-DPCC method is proposed to improve the robustness of the system to the motor parameters by updating the control voltage coefficient matrix,and the sampling current is replaced by the predicted current value at the next time to compensate the influence of the one-beat delay.The effectiveness and robustness of the proposed method under complex operating conditions are verified by comparing simulation and experimental results.
