A process and device for controlling a synchronous motor driving an operating lever in opposition to a friction brake, including a sensor for sensing the position of the lever, and a control computer include: a first regulator defining a nominal control voltage (U*) as a function of a difference (Δω) between the speed of rotation (ω_feedback) of the motor and a set-point speed (ω_cmd); a second regulator determining saturation limits (−Usat; +Usat) of the nominal control voltage as a function of an instantaneous torque provided by the motor; a saturator providing a limited control voltage (U_cmd) on the basis of the nominal control voltage and on the basis of the saturation limits; a converter feeding each winding of the motor with an alternating-voltage signal (U_alim) worked out on the basis of the limited control voltage as a function of the angular position of the motor.
