Design of Longitudinal Control System for Ground Effect Vehicle Based on Auto-disturbance Rejection

Abstract

Design and simulation of vertical pitch attitude and height control system of the ground effect vehicle based on active disturbance rejection control: As for the uncertainty of aerodynamic parameters such as fixed perturbation of the ground effect vehicle, atmospheric disturbance and wave noise, the second-order auto-disturbance rejection controller has been used to control the pitch attitude of the ground effect vehicle and the first-order active disturbance rejection controller has been used to control the altitude to achieve height stability control. The controller designed in this thesis has been verified by simulation in MATLAB, the simulation result showed that the proposed pitch angle ADRC and height ADRC are rational, anti-jamming and robust.
