On reachability of nominal aircraft flight dynamics by data-based control reconfiguration in case of actuator failures

Abstract

The paper proposes the data-based method for reaching and maintaining the nominal aircraft flight dynamics in in case of actuator failures. The method is based on aircraft control reconfiguration and uses input and output data of flight control system only. The novelty of the proposed method lies in the reachability of nominal dynamics not in one, but in several discrete steps from the moment the reconfiguration starts. This makes it possible to ensure the reachability of the desired states for any controllability index of the linear discrete model, as well as to reduce the norms of reconfigured control vectors.
