This volume offers the keynote contributions of the 3rd European Control Conference to be held in Rome in September 1995. It has been edited by Professor Isidori, the Conference Chairman, and presents topics of particular relevance to modern control engineering. None of this material will appear in the full Proceedings. The first part includes ten essays on recent advances in linear-quadratic regulation, robust control and filtering, system parameter identification, automotive control and control of large flexible structures. The invited contributors are leading international experts in their fields. The second part presents the lecture notes of three mini-courses, held in parallel to ECC. The subjects are: feedback stabilisation of non-linear systems, discrete event dynamical systems and computer vision and control.
