Finite-Time Observers: Application to Secure Communication [PDF]
IEEE Transactions on Automatic Control, 2008 In this paper, control theory is used to formalize finite time chaos synchronization as a nonlinear finite time observer design issue. This paper introduces a finite time observer for nonlinear systems that can be put into a linear canonical form up to output injection.

A distributed finite-time observer for linear systems [PDF]
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017 In this paper, the problem of distributed estimation for a linear large-scale system is studied. A nonlinear distributed observer is proposed, whose estimation error converges to zero in a finite time. A fixed-time converging version of the observer is also presented. The efficiency of estimators is demonstrated by computer simulations.

Finite-Time Disturbance Observer of Nonlinear Systems
Symmetry, 2022 In practical applications, for highly nonlinear systems, how to implement control tasks for dynamic systems with uncertain parameters is still a hot research issue. Aiming at the internal parameter fluctuations and external unknown disturbances in nonlinear system, this paper proposes an adaptive dynamic terminal sliding mode control (ADTSMC) based on ...

Design of a distributed finite-time observer using observability decompositions [PDF]
2019 18th European Control Conference (ECC), 2019 In this paper, a distributed observer is presented to estimate the state of a linear time-invariant plant in finite-time in each observer node. The design is based on a decomposition into locally observable and unobservable substates and on properties of homogeneous systems.

Finite-time observer design of a class of nonlinear systems [PDF]
Archives of Control SciencesWe consider the problem of global finite-time stability for a class of nonlinear systems. The novelty in this paper is to consider a nonlinear finite time observer design, which introduces a finite-time observer for nonlinear systems that can be put into

Finite time estimation through a continuous‐discrete observer [PDF]
International Journal of Robust and Nonlinear Control, 2018 SummaryWe study two broad classes of nonlinear time‐varying continuous‐time systems with outputs. For the first class, we build an observer in the case where a state dependent disturbance affects the linear approximation. When the disturbances are the zero functions, our observer provides exact values of the state at all times larger than a suitable ...

Robust Finite-Time Output Feedback Control for Systems With Unpredictable Time-Varying Disturbances
IEEE Access, 2020 This work presents a robust finite-time output feedback control method for a number of nonlinear systems that suffer unpredictable time-varying disturbances. The developed method takes advantage of control techniques based on a finite-time state observer
