ABSTRACT:
One embodiment includes an internal combustion engine, a sensor signal representative of an observed engine speed, and a controller. This controller is responsive to the sensor signal to determine a control input representative of a difference between the observed engine speed and a desired engine speed. The controller defines a compensator that is one or more of a proportional-integral type, a proportional-derivative type, and a proportional-integral-derivative type. The controller determines at least one gain factor of the compensator with a signal corresponding to engine load. The compensator is responsive to the control input to generate an output signal to adjust engine fueling as a function of the control input and the gain factor.
