二阶LADRC在风电并网逆变器网侧直流母线电压控制中的运用
Application of second-order LADRC in grid side DC bus voltage control of wind power grid-connected inverter
摘要
Abstract
In order to improve the stability and dynamic response speed of the DC bus voltage of the grid side inverter in the wind power grid-connected system,a second-order linear active disturbance rejection control(LADRC)without object model assistance is designed to replace the PI controller of the voltage outer loop,thus forming a novel double closed-loop control structure.In this paper,the frequency domain analysis method is utilized to analyze the stability,tracking and anti-interfer-ence ability of ADRC controller.Finally,the feasibility of the proposed control structure is verified in the physically realized mechatronic systems of 3.6MW direct drive permanent magnet synchronous wind turbine,and the control effect of traditional PI control and the control mode proposed in this paper is carried out comparison under different working conditions.The experimental results show that the control scheme designed in this paper is superior to the traditional PI controller,and has good anti-interference and robustness,greatly reducing the impact of DC side bus voltage fluctuation.关键词
