Abstract:

The scope of this mini-course is to presents the formulation of distributed parameter systems in terms of port-Hamiltonian system. At first it is shown, for different examples of physical systems defined on one-dimensional spatial domains, how the Dirac structure and the port-Hamiltonian formulation arise from the description of distributed parameter systems as systems of conservation laws. Then, we consider systems of two conservation laws, describing two physical domains in reversible interaction, and it is shown that they may be formulated as port-Hamiltonian systems defined on a canonical Dirac structure called canonical Stokes-Dirac structure. This canonical Stokes-Dirac structure can be generalised for the examples of the Timoshenko beam, a nonlinear flexible link, and the ideal compressible fluid in order to encompass geometrically complex configurations and the convection of momentum. Energy-based spatial discretisation and model reduction techniques are also presented to illustrate possible ways to simulate and operate with such class of dynamical systems..

报告人简介：

Alessandro Macchelli (1975) took the Laurea Degree cum laude and the PhD in Automatic Control and Operational research at the Department of Electronics, Computer Science and Systems (DEIS) of the University of Bologna in 2000 and 2003, respectively.  He has been visiting scholar (sponsored by NACO2) at the University of Twente (The Netherlands) in 2001 and Post-Doc in 2003, cooperating with Prof. A. van der Schaft and Prof. S. Stramigioli. In 2004, he got a Post-Doc position at Department of Electronics, Computer Science, and Systems (DEIS) of the University of Bologna, and in April 2005, he joined DEIS as assistant professor in robotics and industrial automation. After 2005, he has been visiting professor at the Tongji University (Shanghai, China), at the Institute of Automatic Control and Control Systems Technology of the Johannes Kepler University Linz (Austria), and at the National Engineering Institute in Mechanics and Micro-technologies (FEMTO-ST / AS2M) in Besançon (France). His research activity is mainly focused on port-Hamiltonian systems, with particular emphasis on modelling, simulation and control of distributed parameter systems, and applications of the port-Hamiltonian framework to robotics and mechatronics. He is currently author of more than 50 journal and conference papers on these topics.
