Dissipativity is a fundamental property of any pyhsical system which is deeply routed in energy conservation. In the context of systems and control, which always deals with open systems as control inputs and system outputs act across the system boundary, dissipativity was introduced in the seminal 1972 paper of Jan C. Willems. Nowadays many different flavours of dissipativity are considered in systems and control ranging from port-Hamiltonian systems via reachability analysis of dynamic systems to the dissipativity analysis of optimal control problems (which was also pioneered by Willems in a 1971 publication in the IEEE Transactions on Automatic Control).
The bi-annual Brig Workshop on Dissipativity in Systems and Control provides a forum to discuss the wide range of research topics based on dissipativity notions and dissipation inequalities. The workshop is organized by Prof. Matthias Voigt from the UniDistance Suisse, Dr. Benjamin Unger from the University of Stuttgart, and Prof. Timm Faulwasser from TUHH.
