Robust Fixed-Time Stability: Application to Sliding-Mode Control [PDF]
IEEE Transactions on Automatic Control, 2022 This article deals with robust fixed-time stability and stabilization. First, new global robust fixed-time stability results are proposed for scalar systems by using constant and variable exponent coefficients. Then, they are applied to global robust fixed-time stabilization of a class of uncertain nonlinear second order systems by using sliding mode ...

A Robust Observer-Based Control Strategy for n-DOF Uncertain Robot Manipulators with Fixed-Time Stability [PDF]
Sensors, 2021 In this paper, a robust observer-based control strategy for n-DOF uncertain robot manipulators with fixed-time stability was developed. The novel fixed-time nonsingular sliding mode surface enables control errors to converge to the equilibrium point ...

Global Fixed-Time Stability of General Stochastic Nonlinear Systems
ComplexityIn this article, the fixed-time stabilization issue is investigated for a kind of general p-norm stochastic nonlinear systems. The feature of the considered systems is that all powers are any positive rational numbers, which means this type of systems ...

Nonsingular Global Fixed‐Time Stabilization for Nonlinear Systems [PDF]
Complexity, 2021 Since existing results about fixed‐time stabilization are only applied to strict feedback systems, this paper investigates the nonsingular fixed‐time stabilization of more general high‐order nonlinear systems. Based on a novel concept named coordinate mapping of time domain, a control method is first proposed to transform the nonsingular fixed‐time ...

On Finite/Fixed-Time Stability Theorems of Discontinuous Differential Equations
Mathematics, 2022 We investigated the finite/fixed-time stability (FNTS/FXTS) of discontinuous differential equations (DDEs) in this paper. To cope with differential equations that were discontinuous on the right-hand side, we utilized the Filippov solution, which is ...

Fixed-Time Fractional-Order Sliding Mode Control for UAVs under External Disturbances
Fractal and Fractional, 2023 The present paper investigates a fixed-time tracking control with fractional-order dynamics for a quadrotor subjected to external disturbances. After giving the formulation problem of a quadrotor system with six subsystems like a second-order system, a ...

Fixed‐time output stabilization and fixed‐time estimation of a chain of integrators [PDF]
International Journal of Robust and Nonlinear Control, 2018 SummaryA solution to the problem of global fixed‐time output stabilization and estimation of a chain of integrators is proposed. A nonlinear scheme comprising a state feedback controller and a dynamic observer are designed to guarantee both fixed‐time estimation and fixed‐time control.
