4 Preface This volume contains the proceedings of HART'97, the international workshop on Hybrid And Real-Time systems, held in Grenoble, France, March 26-28, This workshop, sponsored by the European Community research grant HYBRID EC-US-043, was preceded by several formal and informal meetings, at Ithaca, New York (1991, 1994, 1996), Lyngby, Denmark (1992), Boston, Massachusetts (1993), Grenoble, France (1995) and New Brunswick, New Jersey (1995). The proceedings of some of these workshops can be found in volumes 736, 999, and 1066 of the Springer-Verlag Lecture Notes in Computer Science series. The focus of the workshop was on mathematical methods for the rigorous and systematic design and analysis of hybrid systems. A hybrid system consists of digital devices that interact with analog environments. Driven by rapid advances in digital controller technology, hybrid systemsare objects of investigation of increasing relevance and importance. The emerging area of hybrid systems research lies at the crossroads of computer science and control theory: computer science contributes expertise on the digital aspects of a hybrid system, and control theory contributes expertise on the analog aspects. Since the two research communities speak largely different languages, and employ largely different methods, it was the purpose of the workshop to bring together researchers from both computer science and control theory. The three-day workshop featured 2 tutorial surveys, 5 invited presentations and 31 contributed papers (22 regular and 9 short), which were refereed and selected by the program committee before the workshop. I would like to thank the program committee members, R. Alur (Bell Labs), Z. Artstein (Weizmann), E. Asarin (Moscow), T. Henzinger (Berkeley), B. Krogh (CMU), Y. Lakhnech (Kid), K. Larsen (Aalborg), N. Lynch (MIT), S. Nadjm-Tehrani (Linkoping), A. Pnueli (Weizmann), J. van Schuppen (CWI), E. Sontag (Rutgers), P. Varaiya (Berkeley) and F. Vaandrager (Nijmegen) for the effort they invested in the refereeing process. The help of the sub-referees J. Andersen, A. Bouajjani, M. Broucke, A. Deshpande, K. Havelund, K. Kristoffersen, J. Malec, T. Padron- McCarthy, C. Petersohn, A. Puri, A. van der Schaft, A. Skou, J. Springintveld, J. Stroemberg, and L. Urbina is gratefully acknowledged. We are grateful to all invitees and contributors for making the workshop a success. In addition, I would like to thank my colleagues Sergio Yovine and Ahmed Bouajjani for their help, Chantal Costes for taking care of all the organizational details, and Joseph Sifakis and the rest of VERIMAG members for creating and maintaining an environment in which all this could happen.
