Grid-connected current control of photovoltaic inverter based on linear active disturbance rejection control
摘要
Abstract
In order to suppress the internal uncertainties and external disturbances in photovoltaic grid-connected inverter, this paper presents a linear auto-disturbance rejection control strategy for on-line current tracking. Based on the topology of the full - bridge photovoltaic inverter, a second- order linear auto - disturbance - rejection control model is established, and its control parameters are analyzed and optimized. Then the robustness of the system is improved by the fast tracking of the second - order linear auto - disturbance rejection controller. Finally, the linear auto-disturbance-rejection control system is simulated by Matlab/Simulink.The simulation results show that the linear auto-disturbance rejection control strategy can quickly track the grid current, and meanwhile can effectively suppress the internal uncertainty and external disturbance.关键词
