Abstract :
A physically based, nonlinear model of the masses of air and burned gas inside the cylinders of a spark ignition (SI) engine is presented. Goal of this work is to develop a feed forward control law, which perfectly tracks given reference values of these masses. This is done by utilizing the exact linearization approach [1]. The final feed forward control law is verified in combination with a slightly modified design model as well as the original model.
