A method for the control of an electromagnetic actuator (1, 125) coupled to a respective valve (2, 126) and provided with a moving member (3, 127) actuated magnetically, by means of a net force (F), in order to control the movement of the valve (2, 46) between a closed position (ZSUP) and a position of maximum opening (ZINF), a pair of electromagnets (6, 129) disposed on opposite sides with respect to the moving member (3, 127) and an elastic member (7, 30) adapted to maintain the valve in a rest position. The method comprises the stages of estimating the disturbing forces (AF) acting on the valve (2, 46), calculating an actual force (FE) as a function of the objective force value (Fo) and the disturbing forces (AF) and implementing this actual force value (FE). <IMAGE> |
