摘　　要：基于有限控制集模型预测控制(FCS-MPC)的并网逆变器存在预测电流误差,且滤波器电感参数失配将会进一步增大该误差的问题,提出了基于自适应误差校正的并网逆变器模型预测控制(MPC)方法。首先建立基于FCS-MPC的并网逆变器模型,研究了预测电流误差产生的原因;然后在电流预测模型中加入误差校正环节,通过扩展卡尔曼滤波器(EKF)实时辨识滤波器电感参数,能在电感参数失配的情况下自适应地修正MPC的参考电流,抑制网侧电流谐波分量。最后,通过仿真验证了所提方法的有效性。A model predictive control(MPC)method for the grid-connected inverter based on adaptive error correction is proposed to address the problem that the grid-connected inverter based on the finite control set model predictive control(FCS-MPC)experience prediction current errors,and the mismatch of filter inductance parameters can further exacerbate these errors.Firstly,a model of the grid-connected inverter based on FCS-MPC is established,and the causes of the prediction current errors are studied.Then,an error correction link is added to the current prediction model.By using the extended Kalman filter(EKF)to identify the filter inductance parameters in real time,the MPC reference current can be adaptively corrected when the inductance parameters are mismatched,and the harmonic components of the grid-side current can be suppressed.Finally,the effectiveness of the proposed method is verified by simulations.
