A Tribute to George Zames

The first paper in this issue, Adaptive Control: Towards a Complexity-Based General Theory, was prepared by George Zames to be delivered as a plenary paper during the Second IFAC Symposium on Robust Control Design, which was held from June 25 to 27, 1997, in Budapest, Hungary. When the time came to leave for Budapest, however, George was too ill to go, and the plenary paper was not presented. Upon hearing the news the participants of the Symposium sent a letter signed by everyone, wishing George a fast recovery. He died on August 10. His obituary appeared in the March, 1998, issue of  Automatica (Volume 34, p. 285.)

Papers that are not presented at IFAC meetings are normally not included in the proceedings but this paper does appear in the proceedings of the Robust Control Design Symposium. The paper is devoted to a theme that engrossed George during his last years. He lectured about it at several other conferences. Because the theme is important and interesting, and the paper is one of the last that George prepared, the text that he submitted for the Robust Control Symposium is included in the present issue of Automatica unabridged and unedited, as a tribute to the memory of George Zames.
