Modeling and Simulation of Linear Active Disturbance Rejection Controller in Simulink

Abstract

The principle and structure of linear active disturbance rejection controller(LADRC) are analyzed, and the algorithm of the controller is clarified and the parameter setting process is simplified. Completing the creation and packaging of functional modules of linear active disturbance rejection controller by Simulink modeling idea and creating a module library of linear active disturbance rejection controller. The validity of linear active disturbance rejection controller and the effectiveness of the modeling method are described by linear active disturbance rejection control simulation of a second—order nonlinear time—varying object.
