SCO colloquium: Arjan van der Schaft

Abstract: The list of scientific contributions of Jan Willems spans a whole range of topics, including (input-output) stability theory, dissipativity theory, linear geometric control theory, identification, the behavioral approach to systems and control, physical systems theory, open stochastic systems, .. ; see the website https://homes.esat.kuleuven.be/~sistawww/smc/jwillems/ for much more information. In this talk I will focus on two of these topics: dissipativity theory, and the behavioral approach to systems and control. Discussion of the first topic will be partly based on:

 

Part I: General Theory, 50 Years of Dissipativity Theory, IEEE Control Systems Magazine 42 (2), 46-50, 2022,

Part II: Linear Systems With Quadratic Supply Rates, IEEE Control Systems Magazine 42 (3), 32-35, 2022.
