Abstract
In this dissertation the waste incineration process has been described, an overview of the state
of the art control methodologies given and a new approach, based on input/output linearization
and extremum seeking has been presented. This approach has been tested on a model appositely
designed. The results have shown that it is possible to control the waste bed temperature
to certain reference values, with robustness against changes in the waste composition. It is
furthermore possible to identify reference values for the waste bed temperature such as the
steam
ow rate is maximized, while at the same time fulfilling operational constraints.
