Vibration Suppression of a Coupled Aircraft Wing with Finite-Time Convergence
Complexity, 2022 A nonlinear coupled wing model subject to unknown external disturbances is proposed in this paper. Since the model is modeled by partial differential equations, the traditional control design scheme based on the ordinary differential equation model is ...

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 ...

A Novel Active Fault-Tolerant Tracking Control for Robot Manipulators with Finite-Time Stability
Sensors, 2021 Many terminal sliding mode controllers (TSMCs) have been suggested to obtain exact tracking control of robotic manipulators in finite time. The ordinary method is based on TSMCs that secure trajectory tracking under the assumptions such as the known ...

New Finite-Time and Fast Converging Observers With a Single Delay [PDF]
IEEE Control Systems Letters, 2022 We provide new reduced order observer designs for a key class of nonlinear dynamics. When continuous output measurements are available, we prove that our observers converge in a fixed finite time in the absence of perturbations, and we prove a robustness result under uncertainties in the output measurements and in the dynamics, which bounds the ...

Gaussian quantum entanglement in curved spacetime
Results in Physics, 2023 The influence of Hawking radiation on quantum entanglement for bimodal Gaussian states near a Schwarzschild black hole is investigated. It is shown that for a thermal squeezed state of a bimodal bosonic system the Hawking radiation reduces and even can ...

Global finite-time observers for non linear systems [PDF]
Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009 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.

Adaptive Terminal Sliding Mode Control for Reentry Vehicle Based on Nonlinear Disturbance Observer
IEEE Access, 2019 The movement of reentry vehicle is disturbed by the atmospheric environment and changes of aerodynamic parameters. In this paper, an adaptive terminal sliding mode control method based on nonlinear disturbance observers is proposed, which is used to ...
