<p>Device for controlling the positioning of variable-geometry equipment (1) of a turbomachine, comprising a computer (2), an actuator (5) of said variable geometry, driven by the computer (2), said actuator (5) comprising a moving assembly (6) equipped with a sensor (8) for measuring the elongation of the assembly. The device also comprises a drive train (7) connected to a point of attachment (12) for the moving assembly (6) at one end and to a mounting point (13) for the equipment (1) at the other end. Under the action of the actuator (5), the mounting point (13) moves along a travel path limited by an end stop (11). The drive train (7) can be elastically deformed under the action of the actuator (5) when the mounting point (13) rests against the end stop (11). The device is characterized in that the computer comprises a module for resetting the value of the elongation of the moving assembly (6), said value corresponding to the contact between the mounting point (13) and the end stop (11). The module sends at least one instruction to the actuator (5) to move the moving assembly (6) beyond the position corresponding to the position in which the mounting point (13) abuts the end stop.</p> |
