This book contains the text of the plenary lectures and the mini-courses
of the European Control Conference (ECC'93) held in Groningen, the
Netherlands, June 2S-July 1, 1993. However, the book is not your usu- al
conference proceedings. Instead, the authors took this occasion to take
a broad overview of the field of control and discuss its development
both from a theoretical as well as from an engineering perpective. The
first essay is by the key-note speaker ofthe conference, A.G.J. Mac-
Farlane. It consists of a non-technical discussion of information
processing and knowledge acquisition as the key features of control
engineering tech- nology. The next six articles are accounts of the
plenary addresses. The contribution by R.W. Brockett concerns a
mathematical framework for modelling motion control, a central question
in robotics and vision. In the paper by M. Morari the engineering and
the economic relevance of chemical process control are considered, in
particular statistical quality control and the control of systems with
constraints. The article by A.C.P.M. Backx is written from an industrial
perspec- tive. The author is director of an engineering consulting firm
involved in the design of industrial control equipment. Specifically,
the possibility of obtaining high performance and reliable controllers
by modelling, identifi- cation, and optimizing industrial processes is
discussed.
