摘　　要：相比传统d,q轴解耦控制方式,并网逆变器三矢量模型预测电流控制(3V-MPCC)稳态性能好,动态响应快,但存在计算量大的缺点。为此,本文提出一种基于期望扇区选择的优化三矢量模型预测电流控制(03V-MPCC)算法。首先介绍传统3V-MPCC,然后提出令预测电流为期望电流,根据无差拍控制原理快速确定期望扇区的优化算法。最后搭建以STM32F407VET6为核心的实验平台进行验证。结果表明:所提算法有良好的稳态与动态控制性能,同时大幅缩短了算法执行时间。Compared with the traditional d,q decoupling control method,the three-vector model predictive current control(3V-MPCC)of grid connect inverter has better steady state performance and faster dynamic response,but it has the disadvantage of large computational volume.For this reason,an optimal three-vector model predictive current con-trol(O3V-MPCC)algorithm is proposed based on desired sector selection.Firstly,the traditional 3V-MPCC is introduced and then the optimisation algorithm is proposed to make the predicted current as the desired current and the desired sector is quickly determined according to the principle of dead-beat control.Finally,an experimental platform with STM32F407VET6 as the core is built for verification.The results show that the proposed algorithm has good steady state and dynamic control performance,at the same time significantly reduces the execution time of the algorithm.
