(EN) DISTRIBUTED ACCELERATION SENSING FOR ROBUST DISTURBANCE REJECTION
(FR) DÉTECTION D'ACCÉLÉRATION DISTRIBUÉE POUR UN REJET DE PERTURBATION ROBUSTE
Abstract
(EN)
An aerial vehicle comprising an airframe, an aircraft flight controller to provide an output control signal, and a planar printed circuit board positioned on the airframe. The printed circuit board may include coupled thereto a processor, a rate gyroscope, and at least three accelerometers. The processor is configured to generate an actuation signal based at least in part on a feedback signal received from at least one of said rate gyroscope and the at least three accelerometers. The processor communicates the actuation signal to said aircraft flight controller, which is configured to adjust the output control signal based on said actuation signal.

L'invention concerne un véhicule aérien comprenant une cellule, un dispositif de commande de vol d'aéronef pour fournir un signal de commande de sortie, et une carte de circuit imprimé plane positionnée sur la cellule. Un processeur, un gyroscope de vitesse et au moins trois accéléromètres peuvent être couplés à la carte de circuit imprimé. Le processeur est configuré pour générer un signal d'actionnement sur la base, au moins en partie, d'un signal de rétroaction reçu en provenance dudit gyroscope de vitesse et/ou desdits au moins trois accéléromètres. Le processeur communique le signal d'actionnement audit dispositif de commande de vol d'aéronef, qui est conçu pour ajuster le signal de commande de sortie sur la base dudit signal d'actionnement.
