Adaptive Fuzzy Inverse Optimal Fixed-Time Control of Uncertain Nonlinear Systems
IEEE transactions on fuzzy systems, 2022Most existing methods on optimal finite-time control are restricted to a complex design and learning procedure, and only practical finite-time stable is ensured, which greatly limits the desirable performance of optimal and finite-time control.

This paper studies the trajectory tracking problem of unmanned surface vehicle subject to unmeasurable velocities and unknown disturbances. By combining a fixed-time extended state observer (FESO) and a fixed-time differentiator, a fixed-time sliding mode control (FTSMC) law is proposed, in which a saturation function is adopted to make the terminal ...

Fixed-Time Learning for Optimal Feedback Control
Volume 10: 19th International Conference on Multibody Systems, Nonlinear Dynamics, and Control (MSNDC), 2023Abstract In this paper, we introduce the problem of fixed-time optimal stabilization to construct feedback controllers that guarantee closed-loop system fixed-time stability while optimizing a given performance measure. Specifically, fixed-time stability of the closed-loop system is established via a Lyapunov function satisfying a ...

Adaptive fixed-time control for Lorenz systems
Nonlinear Dynamics, 2020This paper focuses on the problem of fixed-time chaos suppression and stabilization of a class of Lorenz systems with uncertain parameters. Based on the fixed-time stability theory, adaptive control and backstepping algorithm, a novel adaptive practical fixed-time controller is proposed.

Nonsingular Fixed-Time Integrated Guidance and Control
2021A backstepping-based nonsingular fixed-time integrated guidance and control strategy is proposed. To avoid the appearance of singular terms in the time derivatives of virtual control laws, new nonsingular fixed-time control laws and new nonsingular fixed-time filters are designed based on the sigmoid function.
