This thesis presents a practical implementation of fault detection scheme in a real
system by using residuals signals. These residuals have been generated applying the
method of a model-based fault diagnosis. Different approaches have been studied
and the corresponding algorithms developed. The object of the investigation is
the three tank system in which different kind of methods of fault detection were
performed. Various scenarios in which faults are simulated in actuators, sensors or
components are analyzed considering also the presence of noise. Due to the inherent
system characteristics it presents four possible work regions which are usually not
taken into account in literature, but studied in this thesis. Also special cases, when
the system goes from one region to another through critical points in which the
system presents singularities, are shown. Faults will be performed around the time
when the system states lie in the neighborhood of the critical points and the main
task is now to overcome these singularities and achieve successfully a fault detection. / Tesis
