Yiming Chen is a Full Professor of the College of
Science of Yanshan University since 1998. He was
the Dean of the College of Science of Yanshan
University for 14 years (from 1998 to 2012).
Until now, Prof. Chen has published more than 140
international journal articles and international
conference articles and contributed 5 co-edited
special books. Moreover, he has achieved 5
research projects. He is the membership of
Chinese Society of Induction and Applicative
Mathematics, Chinese Society of Computing
Mechanics and Chinese Society of Mathematics.
Prof. Chen has organized two international
conferences in 2010 and 2011, respectively.
Prof. Chen has earned First Award of Science
and Technology Progress of China Ministry of
Mechanical Industry and Third Award of Education
of Hebei Province in 1999 and 2000, respectively.
In 2010, he has been certificated as a valued
reviewer by ELSEVIER publisher.
Prof. Driss Boutat
Host scientist
Driss Boutat has been a Full Professor in ENSIB
since 2008, which developed into the INSA Centre
Val de Loire in 2014. Until now, Prof. Boutat has
published more than 110 international journal
and international conference articles. Moreover,
he is supervisor of 12 PhD students. Prof. Boutat
earned the National order of France: Order of
Academic Palms Chevalier (Knight) since January
2010, the National Award for doctoral supervision
and research from 2008 to 2012, and the French
Excellent Scientist Award since 2012. In 2011,
he was selected in Who’s Who in the World.
Recently, he received the Best Paper Award in
the 7th International Conference on Bio-inspired
Systems and Signal Processing. From 2017 to
2021, Prof. Boutat is appointed as a foreign expert
of high level by the Chinese government. In 2019,
Prof. Boutat nominated as Guest Professor by
Shenyang Jianzhu University (from 2019 to 2022).
The proposed research project is on observer design for Distributed-Parameter
Systems (DPSs) and Fractional Order Systems (FOSs). This is an interdisciplinary
research project where the conception of observer is applied to DPSs and FOSs,
and the obtained results are applied to nonlinear acoustics and viscoelastically
damped structures. New research activities are being developed, which are
complementary to those of the teams involved in the project.
Estimation of the states of DPSs and FOSs is important for engineers and
scientists. However, research on observer design for these systems has not
been as extensive as in the case of Lumped-Parameter Systems, especially in
nonlinear case. Consequently, the achievements to date of this research project
are outlined as follows with the involvements of the partners:
1. Development of the Nonlinear Observer Canonical Forms for nonlinear
DPSs and FOSs in order to easily apply existing observer design methods
(cooperation of Prof. Chen, Prof. Boutat and Dr Liu);
2. Design of new observers for nonlinear DPSs and FOSs (with unknown
inputs or not), such as proportional and integral observers, adaptive
observers, and interval observers (cooperation of Prof. Chen, Prof. Boutat
and Dr Liu);
3. Development of efficient numerical algorithm for considered equations,
and new robust differentiators using wavelets, etc. (cooperation of Prof.
Chen, Prof. Boutat and Dr Liu);
4. Application of the concept of observer to solve nonlinear acoustics
equations. The obtained results will also be applied to context of new
ultrasonic “pulse-echo” imaging for Non Destructive Testing applications
(cooperation of Prof. Chen and Dr Dos Santos);
5. Study on various aspects of fractional models for damped structures, using
observer design. In particular, the system parameters will be identified
(cooperation of Prof. Chen and Dr Serra).
2019 INTERNATIONAL CONFERENCE ON FRACTIONAL
CALCULUS THEORY AND APPLICATIONS (ICFCTA 2019)
LE STUDIUM CONFERENCES
The 2019 International Conference
on Fractional Calculus Theory and
Applications (ICFCTA 2019) was
held in Bourges, France, from April
25 to April 30 at INSA Centre Val de
Loire premises. It was cosponsored
by the National Institute of Applied
Sciences of Centre Val de Loire
(France), Yanshan University
(China) the Technical Committee
on Fractional Order Systems and
Control of Chinese Association
of Automation. It belonged to
the series of workshops called
«Fractional Calculus Day» organised
by Professor Igor Podlubny together
with Professor YangQuan Chen
from 2007 in different universities
around the world. This conference aimed to provide a platform for researchers
in fractional calculus theory and applications to exchange results and advanced
technology. During the conference, experts and scholars in related fields and
chief editors of well-known magazines will made special reports. More than 40
participants from 11 countries attended the conference (Australia, China, France,
Germany, Oman, Poland, Portugal, Saudi Arabia, Slovakia, Ukraine, USA).
