| 摘要 |
A control method for an electromagnetic actuator (1) for the control of a valve (2) of an engine from an abutment condition, in which an actuator body (4) actuating the valve (2) and disposed to move between two electromagnets (8) is maintained in abutment against a first excited electromagnet (8) and against the action of at least one elastic body (9); in order to bring the actuator body (4) into abutment against a second electromagnet (8), the first electromagnet (8) is de-excited and the second electromagnet (8) is then excited by means of excitation parameters, which are determined as a function of the measurement of the mean value of the disturbance force (Fd) acting on the valve (2) during the stage of de-excitation of the first electromagnet (8). <IMAGE>
