基于自抗扰的单相PWM整流器直接功率控制
Single-Phase PWM Rectifier Power Feedforward Decoupling Control Based on Active Disturbance Rejection
摘要
Abstract
In order to improve the dynamic performance of single-phase two-level PWM rectifier,this paper proposes an improves control strategy based on the dual closed-loop control method of PI control in the traditional outer loop and power feed-forward decoupling direct power control in the inner loop,and introduces a voltage outer loop based on Linear Automatic Disturbance Rejection Control(LADRC)to reduce the overshoot of the DC side voltage and improve the response speed of the system,and enhance its anti-load disturbance ability.Furthermore,on the basis of power feed-forward decoupling control,SOGI is introduced to construct virtual quadrature components to improve the tracking ability of current to voltage on the grid side and improve the dynamic performance of the system.Finally,the system simulation model is established by MATLAB/Simulink and simulates,and the feasibility and effectiveness of the proposed improved control strategy are verified.关键词
