摘要

对于四桥臂有源电力滤波器

模型预测电流控制（MPCC）是一种较为新颖的高性能控制策略

但是该策略确定下一时刻的最优开关状态所需的滚动优化次数较多。为克服该缺点

给出了一种基于分区判断的改进模型预测电压控制策略（MPVC）。借鉴基于αβγ坐标系下的3DSVPWM调制思想

利用2次分区判断过程确定所给定三维空间电压矢量的具体位置

从24组备选开关状态子集中确定最优子集

以此减少滚动优化的次数

提高寻优的效率。仿真结果证实了改进MPVC策略的有效性

且其具有较强的鲁棒性

较MPCC具有更佳的动态性能。

Abstract

For four bridge-arm active power filter

the model predictive current control（MPCC）is a novelhigh-performance control strategy which

however

needs multiples times of rolling optimization whenthe most optimal switching condition of at the next moment. For overcoming the shortcomings

a kind ofmodified predictive voltage control strategy（MPVC）based on partition judgment is given. With reference 3DSVPWM modulation idea based on αβγ coordination system and with the use of two-time partitionjudgment process the specific position of three dimensional space voltage vector is defined. The optimalsubset is selected from 24 groups of alternative switch state subsets so to reduce the number of rollingoptimization and improve optimization efficiency. The effectiveness of the improved MPVC strategy isproved by the simulation result

which has stronger robustness and

compared to the MPCC

betterdynamic performance.
