A PhD position is available in September 2013 at LAAS-CNRS,
Toulouse University(http://www.laas.fr).
Title: Hybrid Techniques for Analysis and Design of Limited
Information Control SystemsDuration: 09/2013 08/2016Application
Deadline: April 21, 2013
Subject: LimICos is an interdisciplinary project funded by the
French National ResearchAgency (ANR) at the frontier of control
theory, information theory, and digitalcommunications. The
objective of this project is to know to what extent
controlledsystems are impacted by imperfections due to
communication between devices; the mainpart of the proposal is
dedicated to the point-to-point scenario, which typically
involvesone controller and one plant in communication but the case
of networked controlledsystem is also investigated. One of the main
goals of LimICos is to model theseimperfections (which imply
information constraints on the system under consideration)and take
them into account both in the performance analysis and design of
the controlsystems. Although the literature on control contains
some preliminary works into thisdirection, there is much space for
innovation and disruptive concepts as advocated by thecontent of
this project.
Within the LimICos project, a PhD thesis is considered, which
will use, within the scope ofthe project, Lyapunov techniques
inspired by the hybrid dynamical systems frameworkpresented in the
book recently published by Andy Teel and co-authors. With these
hybridtechniques, new modeling and control design tools are
available, which are especiallysuited to address the
continuous/discrete phenomena arising in control networks.
Inparticular, the proposed PhD study will address event-triggered
and self-triggered controldesigns that reduce bandwidth usage in
communication networks, in combination withdistributed control
systems that arise in some specific control problems such
asconsensus of multi-agent systems and control of peculiar
distributed physical systems.
The expected outcome of this PhD study is a set of analysis and
design tools that couldbe assessed on a few application studies,
such as control applications in computernetworks, or
consensus/synchronization of drones in flight formations. In light
of theenvisioned applications, it will be relevant to take into
account isolated nonlinearities(saturation, hysteresis, backlash)
within the PhD study.
Keywords: Lyapunov tools, hybrid dynamical systems, distributed
control, consensus andsynchronization, nonlinear systems
Requirements: Master degree in Control Engineering.
The applicant should have very good knowledge of feedback
control systems, nonlinearsystems, and robust control. Experience
with MATLAB/SIMULINK is needed. Experiencewith information theory
will strengthen the application. Effective communication skills
in
English both oral and especially written are needed.
The position is available in September 2013 for three years. The
PhD student will beappointed by public funding with a salary of
around 1400 Euros (free of charges).
Candidates should apply before April 21st, 2013 by sending an
email to Dr. SophieTarbouriech ([email protected]) and Dr. Luca
Zaccarian ([email protected]) with a CVsummarizing university
background and research experiences and with a
motivationletter.
