Abstract
PURPOSE: To prevent a lowering of engine rotary speed, by increasing the preset value of an armature current when the change rate of an electric motor driven pump rotary speed command signal exceeds a prescribed value and moderating a limitation of output torque for rapid load for short length of time.
CONSTITUTION: For fuel control of a diesel engine 1, firstly by outputs of a throttle sensor 23 and rotary speed sensor 2, a rotary speed command signal em of an electric motor driven pump 3 is obtained through a PID compensation circuit 24 or the like. While from a function generator 28 an armature current setting signal Eas corresponding to engine roary speed is obtained, then a deviation between said signal Eas and actual armature current is integrated by an integrator 29 to obtain an electric motor driven pump rotary speed command signal Ei. Here by a differentiator 41 a change rate of the signal em is detected, and if exceeding a prescribed value a prescribed signal Eo is added to the preset signal Eas for a certain time. Ant then the rorary speed command signal Ei is compared with a motor rotary speed command signal Em, then a smaller one of the signals is output from a priority circuit 26 to control a motor 5.
