基于线性自抗扰控制的单相电力电子变压器整流级控制策略
Single-phase power electronic transformer rectifier stage control strategy based on linear active disturbance rejection control
摘要
Abstract
According to the nonlinear characteristic of power electronic transformer,the single-phase power electronic trans-former rectifier stage controlled by traditional PI is sensitive to parameter variation with slow response speed and poor anti-in-terference performance,a voltage loop control strategy based on linear active disturbance rejection control(LADRC)is pro-posed in this paper.The control strategy has the characteristics of fast response,small overshoot and strong robustness.The model of triple cascaded H-bridge rectifier is built and simulated in Matlab/Simulink.Compared with the traditional PI controller,the simulation results show that the proposed control strategy is more superior and effective.关键词
