A Note on Distributed Finite-Time Observers [PDF]
IEEE Transactions on Automatic Control, 2019 The robust distributed estimation for a class of time-invariant plants is achieved via a finite-time observer, its error reaching zero after a finite time in the absence of perturbation. Two types of robustness are also shown. First, input-to-state stability with respect to measurement noises and additive perturbations is proven. Second, we demonstrate

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 continuous time model for observer-based frequency tracking
Results in Control and Optimization, 2023 Frequency tracking has been the focus of several research works for decades. One common method is to utilize a state observer to dynamically estimate the frequency of the measured signal.

On finite-time observers for linear systems*
IFAC-PapersOnLine, 2023 This work deals with the problem of finite-time homogeneous observer design for linear systems. Compared to other works, the stability conditions and parameters tuning are formulated using linear matrix inequalities being less conservative. The proposed results are based on the homogeneity property and Implicit Lyapunov Function method. The results are

Finite‐time attitude consensus control for multiple rigid spacecraft based on distributed observers
IET Control Theory & Applications, 2023 The problem of attitude consensus control is addressed for multiple rigid spacecraft under a fixed interaction network where only a subset of followers can obtain the leader's state information. To estimate the attitude and angular velocity of the leader,

On simple design of a robust finite-time observer
2022 IEEE 61st Conference on Decision and Control (CDC), 2022 This paper presents a novel observer that estimates the state of a linear system in the observer canonical form in finite time. Due to the specially selected dynamical gain, the proposed observer is easy to tune and, at the same time, it is robust to external perturbations (e.g., state disturbances and measurement noises). The tuning algorithm consists

A Global High-Gain Finite-Time Observer [PDF]
IEEE Transactions on Automatic Control, 2010 A global finite-time observer is designed for nonlinear systems which are uniformly observable and globally Lipschitz. This result is based on a high-gain approach combined with recent advances on finite-time stability using Lyapunov function and homogeneity concepts.
