ABSTRACT:
A fuel metering control system for an internal combustion engine, having a feedback loop. In the system, the quantity of fuel injection (Tim) to be supplied to the engine (plant) is determined outside of the feedback loop. A first feedback correction coefficient (KSTR) is calculated using an adaptive law, while a second feedback correction coefficient (KLAF(KSTRL)), whose control response is inferior to the first feedback correction coefficient is calculated, using a PID control law. The feedback correction coefficients are calculated such that the plant output (air/fuel ratio) is brought to a desired (desired air/fuel ratio). A Variable(s) of one coefficients is replaced with a value of the other coefficient such that the one coefficient becomes close to the other. Moreover, the second coefficient (KLAF(KSTRL) is used at a time of returning from open-loop to the feedback control.
