Electro-Mechanical Engineering Seminar Series
The model reduction problem for (single-input, single-output) linear and nonlinear systems is addressed using the notion of moment. A re-visitation of the linear theory allows to obtain novel results for linear systems and to develop a nonlinear enhancement of the notion of moment. This, in turn, is used to pose and solve the model reduction problem by moment matching for nonlinear systems, to develop a notion of frequency response for nonlinear systems, and to solve model reduction problems in the presence of constraints on the reduced model.
Speaker information
Professor Alessandro Astolfi , Control and Power Group, Imperial College London. Alessandro Astolfi obtained his PhD from ETH Zurich in 1995 with a thesis on discontinuous stabilization of nonholonomic systems. In 1996 he was also awarded a Ph.D. from the University of Rome “La Sapienza” for his work on nonlinear robust control. Since 1996 he has been with the Electrical and Electronic Engineering Department of Imperial College London, where he is currently a professor in nonlinear control theory. From 1998 to 2003 he was also an associate professor with the Department of Electronics and Information of the Politecnico of Milano. Since 2005 he has been a professor in the Dipartimento di Informatica, Sistemi e Produzione, University of Rome Tor Vergata. His research interests are focused on mathematical control theory and control applications, with a special emphasis on the problems of discontinuous stabilization, robust stabilization, robust control, and adaptive control.
