基于GA-PSO的三电平逆变器闭环控制策略
GA-PSO Based Closed-Loop Control Strategy for Three-Level Inverter
摘要
Abstract
To address the neutral-point voltage fluctuation issue in three-level inverter,a closed-loop control strategy based on genetic particle swarm algorithm(GA-PSO)is designed in this article.First,a space vector is added to the inverter for pulse width modulation,and the neutral-point voltage is sampled and compared with the set threshold.Second,an optimal solution is found for the GA-PSO objective function to regulate the fundamental vector action time to ensure that the neutral-point voltage is controlled within an acceptable range.Finally,modeling simulation experiments are conducted in MATLAB environment,and the results show that the proposed method can keep the fluctuation of the neutral-point voltage within an acceptable range,thus verifying the feasibility and effectiveness of the scheme.关键词
