This book comprises the proceedings of the Recent Developments in Control Theory and Applications workshop held in Toronto, Canada, 29th-30th June 1998 in honor of the 60th birthday of E.J. Davison. While the scope of the workshop was quite broad, the main theme was robust control, decentralized control and applications. Some topics include: - robust control for car steering - flow control for networks - fault diagnosis in discrete event systems. With contributions from distinguished authors of international repute, the material presented here focuses upon new findings in the field of control including interesting applications. As well as being informative, it is a useful tool for practitioners of systems and control to ascertain new developments in the field.
