Research interests
My research interests include some
theoretical and practical aspects of nonlinear dynamical systems. In my
team (VASCO), we are invistigating some interesting topics:
- Observer and control design for nonlinear systems with Takagi-Sugeno fuzzy modeling (Stability, ISS, Set Invariance, Time delay, sampled data,...)
- Fault diagnosis and fault tolerant control of nonlinear systems
- Observer for T-S systems with unmeasurable premise variables
- Applications in biomedical and biological systems, vehicles and industrial systems (Cement mill)
Observer and control design for nonlinear systems with T-S systems
This part concerns the
developement
of different algorithms for state and unknown input estimation and
state/output feedback for nonlinear systems. Takagi-Sugeno modeling
approach is then exploited. The main orientation of these works is the
assumption that the weigthing functions depend, completely of partialy,
on unmeasured or unknown parameters (as the unmeasured states) wich can
represent a larger calss of nonlinear systems compared to the T-S
models with known premise variables.
Fault diagnosis and fault tolerant control
In practical situations,
systems are
often subject to actuator/sensor faults and/or system components. The
objective of this topic is to provide tools and algorithms aiming to
detect, to isolate and to estimate different faults (Diagnosis) by
developing residual generators and fault tolerant controllers based on
state and fault observers.
Vehicle and motorcycle applications
The main objective in
this part is th
application of different control/observation and diagnosis algorithms
in the field of vehicles and motorcycles. These algorithms aims to
assist the riders or drivers:
- Passive assistance: detect dangerous situations and alert the drivers (for example compute the maximal authorized longitudinal velocity in cornering situation).
- Active assistance: detect dangerous situations, alert the drivers and generate an adequate control to avoid this situation (for example lane keeping)
Biomedical and biological applications
Biological systems have attracted
many researchers and a new point of view is provided. This point of
view aims to exploit the rich domain of automatic control and
observation in order to control such systems. For example, the
regulation of the sugar in the blood and the control of tumor growth
by optimal administration of the adequate drugs. Our study
focuses on understanding the mechanism of cell self-controlling,
migrations and mutations. This is in the purpose to develop different
control strategies in the sense of drugs administration, in order to
reduce for example the volume of a localized tumor or its migration.
