CA 2585105

A flight control system is configured for controlling the flight of an aircraft utilizing a three control loop design to robustly increase system performance. An inner loop comprises an improved linear quadratic regulator (LQR) search method, and an outer loop comprises a classic feedback summary gain design. A third loop comprises a steady state trim search method.

L'invention porte sur un système de commande de vol configuré pour commander le vol d'un aéronef au moyen d'un modèle à trois boucles de commande qui permet une augmentation robuste des performances du système. Une boucle interne fait appel à un procédé de recherche de régulateur quadratique linéaire ("linear quadratic regulator" ou LQR), et une boucle externe fait appel à un modèle de gain sommaire à rétroaction classique. Une troisième boucle fait appel à un procédé de recherche d'assiette en régime stable.
