Global Finite-Time Observers for Lipschitz Nonlinear Systems

IEEE Transactions on Automatic Control, 2011
This technical note presents a global finite-time observer design for a class of systems with Lipschitz nonlinearity. By applying a finite-time stability theorem and a careful selection of the homogeneity powers and weights, the problem of global and finite-time stable observers is studied.

An explicit finite difference method for finite‐time observers

International Journal of Robust and Nonlinear Control, 1994
AbstractIn this paper we present a numerical method for estimating the current state of a nonlinear control system. We use finite differences to discretize a modified version of the finite‐time observer equations in James. The discretized equations are simple and easily programmed.

Robust finite time observer design for multicellular converters

International Journal of Systems Science, 2011
In this article, a nonlinear finite time observer is designed for multicellular converters. The aim is to estimate the capacitor voltages by taking into account the hybrid behaviour of the converter. This article extends the validity of the strong Lyapunov function, proposed in Moreno and Osorio (Moreno, J., and Osorio, M.

Semi‐global finite‐time observers for multi‐output nonlinear systems

International Journal of Robust and Nonlinear Control, 2009
AbstractFinite‐time stability is investigated for nonlinear systems, which satisfy uniqueness of solution. First, a new sufficient condition for local finite‐time stability is presented. Next, by using the high‐gain observers and carefully selecting the homogeneity powers and weights, the problem of semi‐global and finite‐time stable observers is ...

Finite Time Observer Design by Probabilistic-Variational Methods

SIAM Journal on Control and Optimization, 1991
A notion of finite time observer for partially observed deterministic control systems is introduced; it is shown how such observers are obtained by probabilistic-variational methods. Observability plays an essential role. The procedure is carried out for finite-state discrete-time systems and continuous-time nonlinear systems, and the observers ...
