Fixed-time observer with simple gains for uncertain systems. (English) Zbl 1372.93047
Summary: In this article, we consider the problem of fixed-time observer for nonlinear systems, that is a finite-time observer whose settling time can be bounded independently of the initial condition. We consider a large class of nonlinear systems which includes two main classes: linearizable systems up to input-output injection and uniformly observable systems. Furthermore, the effect of noise and uncertainty is analyzed.
