An Improved Auto-Disturbance Rejection Control Method for Hypersonic vehicle control system

Aiming at the problem of coupling and disturbance in hypersonic vehicle control system and considering the deficiencies of existing correlative research of auto-disturbance rejection control (ADRC) in this field, this paper proposed an improved ADRC theory, whose main idea is to combine traditional ADRC method with classical control theory so that it can solve the problems of large tracking error, oscillation of rudder angle and difficulty in parameter tuning about the traditional ADRC. Both traditional ADRC method and improved ADRC method have been taken simulation to make a comparison. The simulation results show that the improved ADRC can overcome the shortcomings of the traditional, which means the improved ADRC is feasible and can provide a theoretical reference for designing aircraft control system.
