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 ...

Finite-Time Disturbance Observer for Robotic Manipulators [PDF]
Sensors, 2019 Robotic manipulators may be subject to different types of disturbances such as unknown payloads, unmodeled dynamics, and environment interaction forces. Observing these unknown disturbances in robotic manipulators is fundamental in many robotic applications such as disturbance rejection and sensorless force control.

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 Extended State Observer-Based Fixed-Time Attitude Control for Hypersonic Vehicles
Mathematics, 2022 A finite-time extended, state-observer-based, fixed-time backstepping control algorithm was designed for hypersonic flight vehicles. To enhance the robustness of the controller, two novel finite-time extended state observers were introduced to compensate
