Abstract

PURPOSE: To enable to prevent engine failure, by increasing a controlled variable increasing characteristic on the opposite sides of a blined zone involving an aimed value at the time of controlling the engine speed to the aimed value by increasing the same in comparison to that at the time of controlling the engine speed to the aimed value by lowering the same, in carrying out control on the engine speed at the time idling operation by way of closed loop control.
CONSTITUTION: A blind zone K is formed in a range involving an aimed engine speed N0 for preventing inadvertent operation, and a deviation signal involving the blind zone K is adjusted of its quantity of shift and the gradient of input- output characteristics by a first and a second sampling period setting circuits 56, 57. Here, since an engine has a poor performance to follow up engine speed increasing control the second sampling period setting circuit 57 is designed to have a steep gradient of its characteristic curve. Further, excessive control is eliminated by setting an upper limit value of the controlled variable. Thus, it is enable to accomplish stable control and to increase the degree of freedom in designing the circuitry.
