Abstract
An idle control system for internal combustion engines providing load rejection and/or load compensation for a given engine. speed reference and barometric pressure wherein the present invention accommodates for varying engine speed references and for varying barometric pressures, such as at different altitudes. The control system incorporates a load compensator, and a control structure including a multitude of sub-control blocks. The load compensator generates the needed airflow to compensate for the torque of engine loads and works with a feed-forward controller to reject anticipated loads. The calibration procedure is fully automated.
