The
above threepart article received the AUTOMATICA PRIZE PAPER AWARD at the
10th triennial IFAC World Congress in Munich, July 1987. The award committee's
citation reads:
"These
papers present a fresh theoretical view of systems modelling in a fundamental,
precise, and elegant way. The first part condenses everything that has
been learned about systems theory in the last twenty years in a most beautiful
way. In the second and third part innovative
ideas in identification are
presented and worked out. They are considered to be the best theoretical
papers that have been published anywhere during the past three years."
