摘要

针对八态多电平变换器，提出了一种基于矢量的调制模型预测控制方法，通过合理选择不同工作状态下的基本矢量，使控制误差最小化，并获得较好的动态性能。通过对四电平飞电容升压变换器(4L-FCBC)的仿真验证了所提出的控制策略。结果表明，MMPC的电感电流、飞电容电压和输出电压纹波分别约为MPC的5%、40%和20%。同时，动态响应速度也大大提高。

Modulated Model Predictive Control for Eight-State Multilevel Converters based on the Vector Analysis

This paper presents a vector-based modulated model predictive (MMPC) control for Eight-State Multilevel Converters, which can minimize the control errors and achieve better dynamic performance by properly selecting the fundamental vectors in different operation conditions. A Four-Level Flying Capacitor Boost Converter (4L-FCBC) is simulated to validate the proposed control strategy. The results show that the inductor current, flying capacitor voltage and output voltage ripple of the MMPC are about 5%, 40% and 20% of the MPC, respectively. Meanwhile, the dynamic response speed is also greatly improved.
