基于超螺旋二阶滑模理论的直流微电网母线电压控制
Bus voltage control of DC micro-grid based on super-helix second-order sliding mode theory
摘要
Abstract
Aiming at the problem of bus voltage stability caused by uncertain factors such as load fluctuation and parameter perturbation in DC micro-grid system,a super-helix second-order sliding mode control strategy is proposed in this paper.Firstly,taking the three-phase AC-DC converter of DC micro-grid as the main body,the outer voltage loop controller of three-phase AC-DC converter in DC microgrid is designed through using Super-twisting idea by reasonably selecting sliding mode variables.The controller not only retains the strong robustness of traditional sliding mode,but also effectively reduces the system chattering.Then,according to second law of Lyapunov,the stability conditions of the second-order sliding mode are given.Finally,the feasibility and correctness of the proposed control strategy are verified by numerical simulation.关键词
