An adaptive control system is provided for an internal combustion engine having at least two control inputs which affect an engine output. The system involves establishing a first base value for a first control input as a function of engine operating conditions and establishing a second base value for a second control input as a function of engine operating conditions. Corrections are applied in accordance with a predetermined control strategy to the first base value and the second base value to obtain a first corrected value for the first control input and a second corrected value for the second control input. A particular control input is periodically perturbed, and the engine output is monitored. The actual slope or differential of the engine output with respect to the particular control input is determined. The control strategy is predetermined to cause the actual slope to correspond to a desired value and to allow corrections to be applied to the first and second base values after corrections have become stabilized.

An adaptive control system for an engine having at least two control inputs which affect an engine output, said system comprising: means for establishing a base value for a particular said control input in accordance with engine operating conditions; perturbation means for periodically perturbing said particular control input about said base value; slope determination means, responsive to perturbations of said particular control input, for determining an actual slope of engine output with respect to said particular control input; and control means for controlling a first said control input and a second said control input so as to cause said actual slope to correspond to a desired slope value.
