An idling engine speed controlling apparatus has a feed-back control system to regulate engine speed to a target speed such that a torque disturbance is directly detected to convert it into a signal so that an air-flow rate or ignition timing is controlled on the basis of the sum of the signal and a time-differential of the signal, or such that sub-feed-back compensation is given to the output end of a proportional and integral controller so that an amount of air flowing in a intake air conduit is compensated with the first-order-lag component or an amount of air is controlled in response to the first-order-lag component or the second-order-lag component or the sum of or the difference between these components, or such that an output from the proportional and integral controller or an output from the actuator is fed back to the input side of the controller so as to include a transfer function of the actuator through a detection circuit.

An idling engine speed controlling apparatus for an internal combustion engine comprising: an intake air conduit formed to by-pass a throttle value, an actuator for controlling air flowing in said intake air conduit and a detecting means for detecting an idling speed of said engine to thereby control by feeding back the idling speed to be a predetermined value, said idling engine speed controlling apparatus being characterized by comprising means for detecting a torque disturbance to said engine to convert it into an electric signal depending on the magnitude of the disturbance, and a control means for controlling a parameter of the engine selected from the group of air-flow rate or ignition timing in response to a signal wherein said signal is in proportion to the sum of said electric signal and a time-differential component of said electric signal.
