Abstract

L’invention concerne un système de commande d’une vanne (50) de prélèvement d’air dans un compresseur (4, 6) pour turbomachine. Le système de commande est configuré pour commander l’ouverture/la fermeture de la vanne (50) en utilisant au moins une loi de déplacement de la vanne (50) à partir d’une détermination de différence de pression entre une pression amont (P3) en amont de la vanne (50) et une pression aval (P2) en aval de la vanne (50). Le système de commande est configuré pour déterminer la différence de pression entre la pression amont (P3) et la pression aval (P2) à partir d’une détermination de température (T1), d’une mesure d’altitude de la turbomachine (1), d’une détermination de pression (P0, P1) dans une veine secondaire de la turbomachine (1) et/ou dans le compresseur (4, 6), et/ou d’une détermination de la vitesse de rotation (VR) d’un arbre de turbomachine.
