| Abstract: | When the DC side voltage fluctuation is large,the backstepping method cannot rely on its own robustness to suppress power and DC voltage fluctuations.To this end,this paper will propose a backstepping control algorithm of energy storage converter based on disturbance observer,which can improve the anti-interference performance of the controller and can effectively suppress the DC voltage fluctuation.First,the mathematical model of the two-stage energy storage converter is established and its working principle is analyzed.Then,the controller of the energy storage converter is designed by the backstepping method based on disturbance observer.Finally,simulation in Matlab/Simulink verifies that the backstepping control based on disturbance observer has better robustness and dynamic response performance. |
