โœฆ Synopsis

We provide a method for constructing local observers for some nonlinear systems around a critical point where the linearization is not observable or not detectable. Two examples are provided to illustrate the results of the paper.

This paper is a geometric study of finding general exponential observers for nonlinear systems. Using center manifold theory, we derive necessary and sufficient conditions for general exponential observers for Lyapunov stable nonlinear systems. As an application of our characterization of general ex

ln this paper, we study two important classes of nonlinear systems with perturbation, namely, perturbation with output injection and perturbation of pure feedback systems. With sufficiently good initial error estimates and sufficiently restricted external inputs and perturbation parameter, nonlinear
