A voltage tracking control design of the single-phase inverter based on Linear ADRC

Abstract

This paper analyzes the working principle of the single-phase inverter, studies the problems of slow dynamic response and weak anti-interference ability of the existing PI controller scheme inverter, and designs a linear active disturbance rejection controller. Under this control method, the dynamic response performance and anti-interference ability of the inverter have been significantly improved compared with the PI controller. In this paper, the bandwidth method is used to simplify the design of ADRC and the parameters are set. The control effect is verified by bus jump and load jump. The simulation is carried out in Simulink, and the experimental platform is built to verify the scheme. The simulation and experimental results verify the effectiveness of the LADRC controller, as well as stronger dynamic response performance and anti-interference ability compared with the PI controller.
