摘　　要：为降低传统多矢量模型预测电流控制(MPCC)算法的计算量和复杂度,并保证良好的控制性能,提出了快速筛选第二电压矢量的新型多矢量MPCC算法。根据电流无差拍控制原则,通过直交轴电流差值定义直交轴电流判定因数,简化了第二电压矢量选择过程,减轻了控制芯片的计算量,并保持了低电流脉动的优势。在新型双矢量MPCC算法基础上,提出了结合直交轴电流判定因数和有效电压矢量表用以直接选择第二电压矢量的新型三矢量MPCC算法。实验结果表明,新型多矢量MPCC算法在保持传统多矢量MPCC算法控制性能的同时,新型双矢量MPCC算法的计算量减少33.96%,新型三矢量MPCC算法的计算量减少48.7%。To reduce the computation and complexity of traditional multi-vector model predictive current control(MPCC)algorithm and ensure good control performance,a novel multi-vector MPCC algorithm was proposed to quickly screen the second voltage vector.According to the principle of current non-differ-ential beat control,the d and q-axis current decision factors were defined by the d and q-axis current difference,which simplifies the selection process of the second voltage vector,reduces the calculation of the control chip,and maintains the advantage of low current ripple.On the basis of the new two-vector MPCC algorithm,a novel three-vector MPCC algorithm combining the d and q-axis current decision fac-tors and the effective voltage vector table to directly select the second voltage vector was proposed.Exper-imental results were presented showing that the new multi-vector MPCC algorithm maintains the control performance of the traditional multi-vector MPCC algorithm while the computation of the new two-vector MPCC algorithm is reduced by 33.96%and the computation of the new three-vector MPCC algorithm is reduced by 48.7%.
