Abstract
(EN) A control system (400) for an active inceptor (103) for a fly by wire aircraft permits a zero force null point to settle to a non-zero displacement trim position. An internal position state of a second order mass spring damper model is moved in conjunction with force-displacement characteristic coordinates. This results in no second order dynamics being superimposed on the feel of the inceptor (103) when dynamically adjusting the trim position, thereby eliminating the possibility of any unpleasant buzzing been felt by the operator of the inceptor during a trimming operation.
(FR) Un système de commande (400) pour un organe de pilotage actif (103) destiné à un avion à commande de vol électrique permet à un point zéro de force nulle de se fixer à une position de compensation de déplacement non nulle. Un état de position interne d'un modèle d'amortisseur à ressort de masse de second ordre est déplacé conjointement avec des coordonnées de caractéristique de déplacement de force. Il en résulte qu'aucune dynamique de second ordre n'est superposée à la sensation de l'organe de pilotage (103) lors de l'ajustement dynamique de la position de compensation, ce qui permet d'éliminer la possibilité qu'un bourdonnement d'oreille désagréable ne soit ressenti par l'opérateur de l'organe de pilotage pendant une opération de compensation.
