PREFACE
The thirty-seven papers in this volume cover a wide field of
research activities concerned with the analysis and synthesis of
self adaptive, optimal and multi-level control systems. They re
present the papers submitted to the 2nd IFAC Symposium on "The
Theory of Self Adaptive Control Systems" which was organized by
the Society of Instrument Technology at the request of the United
Kingdom Automation Counci I acting on behalf of the Theory Commit
tee of IFAC under the chairmanship of Prof. John G~ Truxal. The
meeting was held at the National Physical Laboratory, Teddington,
England from September 14-17, 1965 by kind permission of the Di
rector of the Laboratory, Dr. J. V. Dunworth.
The Symposium was attended by 150 people from 17 countries.
The sessions were recorded and the discussions were subsequently
summarized by scientific reporters. These summaries are believed
to correctly convey the essence of the points discussed. Written
discussion remarks, submitted after the Symposium, are reproduced
in ful I, together with the author's reply where appropriate. The
grouping of the papers into symposium sessions has been rearranged
slightly in the Proceedings to accommodate papers which were sub
mitted for post publication only.
The help of alI the organizations and individuals who pre
pared and organized the Symposium, gave papers and contributed to
d(scussions, recorded and edited these discussions and helped
with the editing of the Proceedings is gratefully acknowledged.
