Finite-time observer for the output depending observer form
53rd IEEE Conference on Decision and Control, 2014— This paper investigates the problem of global finite-time observer design for a class of nonlinear systems which can be transformed into the output depending normal form. By introducing the output-dependent gains, we prove that the recent result can be adapted to design a global finite-time observer for the studied normal form.

Finite time observers and observability
29th IEEE Conference on Decision and Control, 1990A notion of finite time observer for partially observed deterministic control systems is introduced. The observer dynamics are given by a Hamilton-Jacobi equation, and the observer is consistent under a natural observability condition. An observability grammian for nonlinear systems is introduced, and is used to study the time evolution of sets of ...

Finite-time observer for nonlinear dynamic systems
1973 IEEE Conference on Decision and Control including the 12th Symposium on Adaptive Processes, 1973This paper introduces finite-time observers for a class of non-linear dynamic systems. The concept of observability is first shown to be a necessary condition for the existence of a finite-time observer for the system. Then a finite-time observer for an important class of systems is constructed with a novel structure which avoids the use of ...

Design of Finite-Time Convergent Functional Observers
2019 8th International Conference on Systems and Control (ICSC), 2019In this paper a finite-time convergence fault estimator based on functional observers is presented. The stability conditions of the observer are given and their performance evaluation is made through numerical simulations.

An Adaptive Finite Time Sliding Mode Observer [PDF]
, 2017 This chapter develops a novel adaptive ?nite time observer which can achieve ?nite time unmatched parameter estimation and ?nite time system state observation. The proposed approach has strong robustness and rapid convergence. A step by step proof is given which employs ?nite time stability and sliding mode principles.

Finite time convergent observers for nonlinear systems
42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004In this note we consider the state estimation problem for nonlinear systems. In a first step we outline the design of an observer for single output nonlinear systems in observer normal form. The estimate of this observer converges to the exact system state within predefined finite time.

Finite-time functional observers for descriptor systems
International Journal of Control, Automation and Systems, 2009This paper deals with the problem of finite-time functional observer design for linear descriptor systems, which converges in finite time exactly. The observer comprises two infinite-time functional observers and a finite delay element. The technique in designing such a class of observers for state-space systems can not be directly applied to deal with

Finite Time Observer Design for Teleoperation System
2019The finite-time output feedback synchronization control problem is considered for a bilateral teleoperation system in the presence of the modeling error and disturbance. A new observer is designed for the velocity estimation by using neural network approximation and fast terminal sliding mode method. It is shown that the resulting velocity error system

Finite-Time Interval Observers’ Design for Switched Systems
Circuits, Systems, and Signal Processing, 2019In this study, a finite-time interval observers’ design method is developed for switched systems suffering from disturbance. First, the interval observer frames for the systems are constructed. Then, sufficient conditions are derived to guarantee that the upper and lower error systems are both positive and finite-time bound. Unlike the current studies,

A Finite Time Functional Observer For Linear Systems
Proceedings of the 44th IEEE Conference on Decision and Control, 2006This paper presents a finite time functional observer for linear systems, i.e., an observer which estimates directly linear functions of the state of a linear system in a predefined finite time. The finite time functional observer is demonstrated on an academic and on a practical example.
