Dr Paul Goulart
I am writing to invite you to the Aerodynamics and Flight Mechanics Research Seminar, which will take place on Thursday 20th September 2012 at 11:15AM in Room 7/3019. Our first speaker in the seminar series is Dr Paul Goulart from ETH Zurich. Details of the talk are as follows:
Title: Stability Analysis of Fluid Flows using Sum-of-Squares Speaker: Dr Paul Goulart (Automatic Control Laboratory, ETH Zurich) Date/Time: Thursday, 20th September 2012 11:15AM (Note time and date is different for this week only!) Venue: Room 3019, Building 7
Abstract:
This talk will describe a new method for assessing the stability of fluid flows governed by the Navier-Stokes equations. Finite-dimensional approximations to the Navier-Stokes equations typically take the form of a set of linear ODEs with an additional nonlinear term that conserves the total energy of the system state. A method for computing Lyapunov functions using sum-of-squares based convex optimization methods that exploits this energy conservation property will be presented for finite dimensional fluid models. These methods can be then applied to infinite dimensional models via robust optimization.
Biography:
Paul Goulart is currently a senior researcher in the Automatic Control Laboratory at ETH Zurich. From 2007 to 2011 he was a lecturer in control systems in the Department of Aeronautics at Imperial College London. He received BSc and MSc degrees in Aeronautics and Astronautics from the Massachusetts Institute of Technology (MIT). He was selected as a Gates Scholar at the University of Cambridge, where he received a PhD in Control Engineering in 2007. From 1998 to 2002 he was an engineer in the Flight Operations Group of the Chandra X-Ray Observatory, and from 2002 to 2003 was a research engineer in the Autonomous Systems Group at the Charles Stark Draper Laboratory. His current research interests include model predictive control, robust optimization and control of fluid flows (http://control.ee.ethz.ch/~goularpa/).
