基于无源-自抗扰的MMC控制策略研究
MMC control strategy based on passivity-active disturbance rejection
摘要
Abstract
To address the problem of poor anti-disturbance performance of the Modular Multilevel Converter(MMC)under the passivity-based control strategy,a novel MMC control strategy based on passivity and active disturbance rejection is pro-posed.First,the Euler-Lagrange(E-L)model of MMC is established and its passivity is proved,on the basis of which an in-ner current loop controller is designed in accordance with the passivity-based control theory.Then,according to the second-order linear Active Disturbance Rejection Control(ADRC)theory,an outer power loop controller is designed and its parame-ters are tuned to compensate for the total disturbance rapidly.This controller provides a fast and stable reference signal for the output of the inner passivity-based controller,thus improving the system tracking performance.Finally,simulations are carried out using MATLAB/Simulink software.Under the power mutation condition,the system responses during start-up and power step are analyzed through comparisons with the PI control and passivity-based control strategies.The results show that the designed control strategy improves the system response speed and anti-disturbance capability,verifying its effectiveness.关键词
