Intelligent adaptive control for the large aircraft based on the disturbance compensation under the influence of strong interferences

Abstract

An intelligent adaptive control scheme based on the disturbance compensation was proposed to solve the stability augmentation control problem of the large under the influence of strong interferences. First, considering the influence of strong wind, the coupling multivariable disturbance observer is designed for the control-oriented model to estimate the synthetical uncertainties and disturbances rapidly and accurately and compensate the close-loop controller. And on the basis of the observer, a novel finite-time robust adaptive controller which is the combination of fast super-twisting algorithm and action dependent heuristic dynamic programming is proposed. The control scheme can obtain good control performance that the large airplane can track the control command accurately and steadily in finite time. Finally, to demonstrate the effectiveness of the proposed intelligent adaptive control scheme, the simulation verification of Boeing 747 is carried out. And the simulation results verify the good control performance in attitude stable and rapid maneuvering of the large aircraft.
