摘要：A method for the control of an electromagnetic actuator (1, 25) coupled to arespective valve (2, 26) and provided with a moving ferromagnetic member (3, 27)
connected to at least one point of the valve, a pair of electromagnets (6, 29) disposed onopposite sides with respect to the moving ferromagnetic member (3, 27) and an elasticmember (7, 30) adapted to maintain the valve in a rest position. The method comprisesthe stages of detecting an actual position (Z) and an actual velocity (V) of the valve (2, 26),determining a reference position (ZR) and a reference velocity (VR) of the valve (2, 26) andminimising differences between the reference position (ZR) and the actual position (Z)and between the reference velocity (VR) and the actual velocity (V) of the valve (2, 26) bymeans of a feedback control action.
