## Control and system theory

Jan van Schuppen, CWI

Control of motorway traffic, of communication networks, of chemical plants, and of manufacturing plants are examples of control. Information technology applied in engineering is based on algorithms from control and system theory. Problems of control and system theory are briefly discussed and related to subjects of mathematics and computer science.

Current research directions are mentioned including control of hybrid systems, of discrete-event systems, of nonlinear systems, and the system theory for these classes of systems including the development of computer algebra.
