To ensure stability of correction of rotor precession movements regardless of speed of rotation of a rotor.
There is provided a command procedure for an active magnetic bearing. The magnetic bearing comprises: a series of electromagnetic actuators, each of which is suitable for exerting radial force on a rotor, forming a stator; a ferromagnetic body forming a rotor that is kept free of contact with the electromagnetic actuators, suitable for being set to rotate around an axis of rotation, and suitable to undergo precession movements in particular; and a sensor that is suitable for detecting radial displacements of the rotor and issuing position signals representative of the radial position of the rotor in relation to the actuators. A stage of calculating at least one actuator command signal comprises a stage of applying at least one transfer function, including several correction coefficients, to a position signal.
