Engine management is today widely developed, because of new severe depollution standards put into effect. Electronic calculators become essential to control so many and complex devices, new sensors and actuators, combined functions, diagnosis...with the required precision and rapidity. New engines, such as gasoline direct injection engines, have to be associated with robust and accurate controllers. In this paper, we focus on a subsystem of the global engine control: the control of the cylinderinlet system, concerning the cylinder flow and its composition (neutral rate in cylinder). For lean burn combustion engines, the recirculated exhaust gases contain a non-negligible part of fresh air added to burnt gas, situation which differs fromstandard stoechiometric applications.This multidimensional and non-linear process implies different control strategies from current ones, with the target of higher robustness and precision. For this purpose, a predictive controller is proposed associated with a model linearization, to reduce computations load.
