<p>A method of calibrating an equilibrium position of an actuator driven by an electric motor with the assistance of a compensating spring, wherein the actuator moves a mechanism and the mechanism opposes the movement with an elastic force, and wherein in the equilibrium position the compensating spring counterbalances the elastic force, includes the following steps:applying a large-amplitude, high-frequency alternating position signal to energize the electric motor, wherein the position signal is biased so that alternating extremes of the position signal straddle the equilibrium position,measuring an actual dynamically variable position of the actuator by means of a position sensor, anddetermining the equilibrium position as that position where the actuator settles.</p> |
