The main
topics of my research are the modelling, study and monitoring of living
systems. My two main application fields are the oceanography (particularly the planktonic
systems) and the biological wastewater treatment processes.
The first
step of my work consist in designing methods to find dynamical models based on
ordinary differential equations (ODE). A good modelling is a very difficult job
that must be performed in strong collaboration with biologists and experts of
the considered process.
Then we
must verify that the model is close to the actual system, this is the
validation step. This task is complex for the non-linear biological systems
that are difficult to measure properly. I develop techniques to determine
qualitatively the transient behaviour of the model and to check if it
corresponds to the experimental observations.
Once the
model is available I design software sensors (or observers) that use the
(partial) available measurements to estimate the non measured variables. These
observer must be as insensitive as possible to the modelling errors.
These
methods use techniques recently developed in the non linear control science
field.
