Control System for Engines Having Multiple Combustion Modes

Abstract: 

A system and method for modeling and controlling an internal combustion engine having multiple combustion modes. The in-cylinder condition is controlled by gas handling devices through both a feed forward and feedback path. The latter path includes an "in-cylinder condition estimator" and a non-linear controller. Fueling parameters are controlled by engine speed, desired torque, and input from the in-cylinder condition estimator.
