Abstract
A system and method for using a sliding mode control algorithm to control flow rates from air handling actuators and fuel injectors of an internal combustion engine. The sliding mode control is based on an engine model that represents the engine in terms of pressure and oxygen content states of the intake and exhaust manifolds (as a linear term) and controllable flow rates (as a nonlinear term).
