The LAGEP (Laboratory of Automatic
Control and Chemical Engineering) develops
its research activities at the interface of
Engineering and Health Sciences leading as
well to base research as well as to transfer
towards the important industrial sector in the
region Rhône-Alpes. Its objective is to gather
the experts in Automatic Control, Chemical
Engineering and Pharmaceutical Engineering
from both the University and the CNRS (Centre
National de la Recherche Scientifique) for the
development of research activities in their
domain of expertise as well as cross-domain
activities organized in the four research themes
presented below.
THEMATIC GROUPS
NONLINEAR SYSTEMS AND PROCESSES
The research topic of the SNLEP team concerns
the theorical development and implementation
of tools in order to: Analyze, Modelize, Simulate,
Control and Optimize Systems in Process
Engineering.
Our theoretical developments are motivated
by practical applications encountered through
collaborations with industrial and academic
partners. More specifically, our work focuses
on model design and reduction, parametric
identification, observation, diagnosis and
control.
PHARMACEUTICAL ENGINEERING
The design of new formulations containing
active molecules is the key point to enhance the
efficiency. These formulations can be fabricated
in the form of capsules or tablets using various
engineering processes in order to control the
active molecules location and distribution inside
the used matrix. The active molecules or the
final drug should answer various criteria driven
by the targeted diseases, application way and
patient’s age.
• Pharmaceutical science (formulation and
• Solid elaboration (lyophilisation and
crystallisation)
• Capsules preparation, colloidal physics and
physical chemistry
• Modelling and process engineering,
• Life science (biodisponibility, skin penetration)
SOLID ENGINEERING
The ‘Solid Engineering’ group is focused on the
study of the solid manufacturing processes from
the initial state (obtained by dissolution, wet
granulation, raw material division) to the final
dry state. Solid particles are mainly obtained by
such processes as crystallization-precipitation,
agglomeration, conductive, convective or spray
drying, freeze-drying. The scope of the group
activities goes from the study of the internal
fundamental mechanisms (heat and mass
transfer, solid phase transition, polymorphism,
desolvatation) to the process monitoring and
control in an industrial context.
PROCESS DYNAMICS AND CONTROL OF
SYSTEMS OF CONSERVATION LAWS
The design of energy efficient, reliable and
intensive processes requires the development
of dynamical models of complex, network
structured processes. Different multi-scale
processes are considered such as adsorption,
reactive extrusion processes, heat pumps,
thermal storages using phase changes
in fluids and cristallization in emulsion
processes, involving mass and heat transport
in heterogeneous and reactive media with
moving interface. Nonlinear control laws are
developped based on their formulation as
port Hamiltonian systems or input-output
contact systems. Control laws for systems of
conservation laws are developed based on the
semi-group theory, Riemann invariants with
recent developments for systems with moving
interfaces.
