The purpose of this paper is to describe systematic analysis and design tools for robust control problems with criteria. We first generalize the Hill–Moylan–Willems framework for dissipative systems to accommodate criteria, and then derive state feedback and measurement feedback synthesis procedures for robust control problems. The information state framework is used for the measurement feedbac...

As a follow-up to the volume Three Decades of Mathematical System Theory that the authors of this paper edited in 1989 at the occasion of the ...ftieth birthday of Jan Willems, we discuss some trends that have become more visible in the past decade. It is argued that system theory is ready to play a role in many di¤erent ...elds of science. Three examples of nontraditional application areas are...

In this paper we study Hilbert space embeddings of dynamical systems and embeddings generated via dynamical systems. This is achieved by following the behavioural framework invented by Willems, namely by comparing trajectories of states. As important special cases we recover the diffusion kernels of Kondor and Lafferty, generalised versions of directed graph kernels of Gärtner, novel kernels on...

In his article "The Suppression of Satirizing Belgian Community Difficulties in Flemish Cinema and the Film Adaptation of Will-O'-the Wisp" Gertjan Willems analyzes two film projects of Frans Buyens. In 1970, Buyens received a positive funding recommendation for Top-Hit Girl, a satire about community difficulties in Belgium. However, Minister of Culture Frans van Mechelen refused to support the...

An important combinatorial result in equivariant cohomology and K-theory Schubert calculus is represented by the formulas of Billey and Graham-Willems for the localization of Schubert classes at torus fixed points. These formulas work uniformly in all Lie types, and are based on the concept of a root polynomial. In this paper we define formal root polynomials associated with an arbitrary formal...

This paper develops a hierarchical control architecture for so called sequential behaviours, i.e. for plant dynamics and specifications that are represented as formal languages of infinite-length words. Our main result is the elaboration of structural properties that (a) allow for abstraction based controller design and that (b) are preserved under closed-loop composition. Thus, we propose to a...

In this paper we study the Markovian properties of a system of linear partial differential equations with constant coefficients as initiated by J.C. Willems. In particular, we prove that his conjecture on Markovianity is true if the characteristic variety of the system has dimension zero. For the case when the system is defined by a differential operator, we give conditions under which the conj...
