An Adaptive Disturbance Rejection Algorithm for Turbulence Compensation of Maneuvering Aircrafts

ABSTRACT A new adaptive disturbance rejection control scheme is proposed for the turbulence compensation of the aircraft in maneuvering flight. The aircraft dynamics in maneuvering flight are studied under random multidirectional turbulence conditions, based on the mutual switching of several “dominant” wind directions, and a piecewise linear system model is established to represent the aircraft dynamics. A new piecewise adaptive control scheme is designed based on the model reference adaptive control when the aircraft in maneuvering flight encounters the turbulence wind in different dominant directions. Desired closed‐loop system stabilization and output tracking have been proven. An aircraft simulation study is shown to verify the effectiveness of our proposed method.
