Abstract (en)

[origin: WO2011121188A1] Electromagnetic actuator (100) having a processing unit (2) designed to act on control means (21) generating a control voltage (Upwm) across the terminals of an actuating coil (3). The processing unit (2) includes first memory means (M1) for storing a first derivative (di1/dton) during a supply period (ton), second memory means (M2) for storing a second derivative (di2/dtoff) during a non-supply period (toff) and computing means (23). Said computing means determine, in succession, a first computing coefficient (A) dependent on the supply bus voltage (Ubus), first and second derivatives (di1/dton, di2/dtoff) and an operating position (x) on the basis of a first correlation between the operating position (x), the first computing coefficient (A) and the electric current (I).
