ABSTRACT:
Disclosed is an electronically controlled fuel injection system for controlling a fuel quantity to be injected each cylinder of a diesel engine by a fuel injection pump (5), wherein a positioning servo system is employed which is arranged to calculate a control input value of an actuator (82) in accordance with a signal from an actual position sensor (84) and a signal from a fuel quantity control unit (2) so that the actual position of a fuel adjustment member (83) is coincident with a desired position thereof indicated by the signal from the control unit (2). The servo system comprises a minimum time control unit (7) and a speed estimation unit (9). The minimum time control unit (7) derives the control input value from a map established on the basis of the nonlinear dynamic model of the actuator (82) as a function of a deviation between the actual and desired positions, a current passing through the actuator (82) and a speed of the fuel adjustment member estimated by the speed estimation unit (9).
