Abstract

This paper presents a design methodology for the rejection of wind gusts during flight. The proposed application is based on the Simple Adaptive Controller (SAC) methodology, but differs from other SAC applications in the sense that the reference model utilised is an Unknown Input Observer (UIO). As a consequence, the adaptive controller is fed by an estimate of the wind gust and will only act in the event of such a disturbance occurring, retaining nominal performance otherwise. Although stability guarantees of the flight control system proposed follows closely previous work, some differences are found and commented upon in this work. Success of the proposed scheme is demonstrated via simulation using a linear model of the MuPAL-α experimental aircraft of the Japanese Aerospace Exploration Agency (JAXA), and the results are compared with an implementation of the original SAC formulation.
