Claim:
1. A device for controlling positioning of an item of variable-geometry equipment of a turbomachine, comprising: a computer; an actuator for actuating the variable geometry driven by the computer and a kinematic system, the actuator comprising a movable assembly including a sensor for measuring its elongation, the kinematic system being connected at one of its ends to a coupling point of the movable assembly and at another end to an attachment point of the item of equipment, the attachment point moving under action of the actuator along a stroke limited by an abutment on which said attachment point is able to abut and the kinematic system configured to be deformed elastically under the action of the actuator when the attachment point is on the abutment, wherein an elongation setpoint supplied by the computer to the movable assembly is defined by taking as reference a value of the elongation of the movable assembly when said attachment point abuts on said abutment.
