Modélisation et commande d'un moteur thermique à allumage commandé

Abstract : This work deals with modeling and control of spark ignition engines with or without
turbocharging. Indeed, the present report is divided into five chapters.
The first chapter is an overview about control oriented modeling, control and estimation
of unmeasured variables of internal combustion engines.
In the second one, models parameters of a downsized three cylinder engine are estimated
and a use of unknown input observers for engine combustion torque estimation is presented.
These models are used in the third chapter to develop some control laws based on Takagi-Sugeno
(TS) fuzzy modeling and control approach. Existing results concerning TS models control for
classical and delayed state cases are presented. In addition, a theoretical result about uncertain TS
models stabilization with H¥ criterion is shown. These models are used in the controllers'
synthesis for air – fuel admission and engine torque control. Then, simulation results are given.
The fourth chapter is a presentation of some obtained real-time results from an engine test
bench.
Finally, in the fifth and last chapter, some current works and perspectives about the
presented work in this report are given.
