A high gain observer for a class of uniformly observable systems

Abstract

Observers are proposed for nonlinear systems. The system is split into two parts. The observer synthesis is performed according to the first part. It is shown that, under structure assumptions made on the second part, arbitrary nonlinearities can be dealt with through a high-gain approach. A consequence of this is that the system is uniformly observable, i.e. observable for every input.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
