Abstract

This paper deals with the nonlinear modelling and control of a turbocharged SI engine. Downsizing based turbocharging is a powerful technique to improve engine performances as fuel economy, pumping loss reduction to increase engine efficiency or driveability optimisation. This method is largely used for diesel engine. For gasoline engines, it is more complex in terms of control. In this work, a simplified control oriented model is presented and validated using a smart MCC three cylinders engine data. Then, based on this model, a fuzzy nonlinear control law is calculated to achieve the fuel consumption and pumping losses reduction by setting the engine states to a given profile
