Interruption in supervisory position control signals can cause problems with respect to actuators which upon loss of such control signals for the actuator will generally slew to a fixed idle position. In such circumstances a machine such as a gas turbine engine in which an actuator is associated will not sustain performance even though there is continued local power supply to the actuator. By utilising a local controller which stores actuator response profiles for certain machine status stages through perturbation or marginal activation of the actuator an appropriate actuator response profile can be chosen and therefore sustaining control signals presented to the actuator to maintain machine operation.

Une interruption des signaux de commande provenant d'un poste de surveillance peut provoquer des problèmes dans des actionneurs, lesquels à la perte de tels signaux de commande basculent généralement en position de repos fixe. Ainsi, en l'absence de signaux de commande, une machine, telle qu'un moteur de turbine à gaz comprenant un actionneur, ne pourra conserver un bon rendement même si l'actionneur continue de bénéficier d'une alimentation en puissance locale. L'utilisation d'un dispositif de commande local qui contient des profils de réponses d'actionneur pour certains stades d'état machine au fil des perturbations ou de l'activation marginale de l'actionneur, permet de choisir un profil de réponses d'actionneur approprié et, ainsi, de présenter des signaux de commande durables à l'actionneur pour maintenir le fonctionnement de la machine.
