The purpose of this lecture is to describe how the classical
notion of steady-state response can be extended to the case of
nonlinear systems and why the proposed extension is useful in
problems of analysis and design. The proposed approach reposes on
a suitable enhancement of the classical concept of limit set in
the theory of dynamical system and finds applications in various
major problems arising in feedback design. The proposed new
framework provides a unified interpretation of a number of
familiar concepts associated with the intuitive idea of
steady-state for linear systems and provides an effective tool to
address various outstanding problem of asymptotic analysis and
design for nonlinear systems. Examples will be presented showing
how the concepts thus developed play an important role in the
analysis of high-gain output feedback closed-loop systems, in the
problem of asymptotic tracking and/or rejection of exogenous
inputs, and in the design of nonlinear observers.
Alberto Isidori is one of the fathers of the geometric approach to nonlinear control that has started to revolutionize the field of nonlinear control some 30 years ago. Since then he has made numerous fundamental contributions to nonlinear control that are now considered the foundations of the discipline. Prof. Isidori was educated in electrical engineering at the University of Rome where he also became a professor in 1975. Since 1989 he has also held a parttime position in the Department of Electrical and Systems Engineering at Washington University in St. Louis. He is author of several highly influential books and has received numerous major prices for his work, including the Giorgio Quazza Medal. This medal is the highest technical award given by the International Federation of Automatic Control.
