Contrôle des systèmes rapides non linéaires - Application au moteur à allumage commandé turbocompressé à distribution variable

Abstract : Spark ignition engine control has become a major issue for the compliance with emissions legislation while ensuring driving comfort.

Engine downsizing is one of the promising ways to reduce fuel consumption and resulting CO2 emissions. Combining several existing technologies such as supercharging and variable valve actuation, downsizing is a typical example of the problems encountered in Spark Ignited (SI) engine control : nonlinear systems with saturation of actuators ; numerous major physical phenomena not measurable ; limited computing time ; control objectives (consumption, pollution, performance) often competing.

A methodology of modelling and model-based control (internal model and predictive control) for these systems is also proposed and applied to the air path of the downsized engine. Models, physicals and generics, are built to estimate in-cylinder air mass, residual burned gases mass and air scavenged mass from the intake to the exhaust.

The complete and generic engine torque control architecture for the turbocharged SI engine with variable camshaft timing was tested in simulation and experimentally (on engine and vehicle). These tests show that new possibilities are offered in order to decrease pollutant emissions and optimize engine efficiency.
