Abstract
The invention concerns a device for the active control of a force feedback for a control device, comprising a calculator, a position sensor () configured to provide the calculator with an effective position signal (Pm) of the control device, and an actuator () ensuring the displacement of the control device at the command of the calculator, the calculator being configured to use the effective position signal and modulate a setpoint current (lc) delivered to the actuator to ensure the position feedback of the displacement of the control device, characterized in that the calculator is further configured to create at least one saturation terminal (Bsat+, Bsat−) according to a predetermined function of the value of the effective position signal of the position/force law kind, and to saturate the setpoint current using the at least one saturation terminal.
