Synchronization of Time-Varying Delayed Neural Networks by Fixed-Time Control
IEEE Access, 2018 This paper discusses synchronization of time-varying delayed neural networks by fixed-time control. First, several new fixed-time stability theorems of the dynamic system are discussed, and the estimation of the convergence time is also gained.

Fixed-Time Convergent Guidance Law with Impact Angle Control
Complexity, 2020 The existing convergence control guidance laws are designed via the Lyapunov asymptotic stability theory or finite-time stability theory. However, guidance law based on the Lyapunov asymptotic stability theory would lead the states to zero only as time ...

Fixed-Time Coverage Control of Mobile Robot Networks Considering the Time Cost Metric
Sensors, 2022 In this work, we studied the area coverage control problem (ACCP) based on the time cost metric of a robot network with an input disturbance in a dynamic environment, which was modeled by a time-varying risk density function.

Fixed‐time attitude tracking control for rigid spacecraft
IET Control Theory & Applications, 2020 This study addresses the fixed‐time attitude tracking for rigid spacecraft with inertia uncertainties and external disturbances. Firstly, a new fixed‐time sliding surface based on the bi‐limit homogeneous theory is proposed. Secondly, a non‐singular sliding mode control is designed to solve the robust fixed‐time attitude tracking problem.

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

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 ...
