The topic of this thesis is system identification and control of two different
internal combustion engines, Partially Premixed Combustion (PPC) engine
and a more conventional Combustion Ignited (CI) diesel engine. The control
of both engines is aimed to emission reduction and to increase the eficiency.
There is an introduction to the internal combustion engine, as well as theory
used about system identification and Model Predictive Control (MPC).
A physical model of a PPC engine was designed. With this model, it was
possible to perform simulations and to obtain data to design a cycle-to-cycle
state space model used subsequently by the MPC controller.
A black box model of the CI engine was designed using data of a real CI
engine from another project. After designing the model, a MPC controller was
created. The aim of this controller was to reduce emissions and to increase
the eficiency of the engine.
