Adaptive Neural Fixed-Time Control for Uncertain Nonlinear Systems
IEEE Transactions on Circuits and Systems - II - Express BriefsThis brief addresses the adaptive fixed-time system control problem subject to unknown nonlinear functions. By employing backstepping technique, fixed-time control, and neural networks (NNs), an adaptive fixed-time control approach is developed.

Fixed-time Attitude Feedback Control for Quadrotor UAV based on Fixed-time Extended State Observer
2021 IEEE International Conference on Mechatronics and Automation (ICMA), 2021Aiming at the nonlinearity, strong coupling and sensitivity to disturbance of quadrotor unmanned aerial vehicle (UAV), an fixed-time attitude feedback control scheme based on fixed-time extended state observer is proposed. Firstly, the virtual controllers are introduced to decouple the system such that the mathematical model is simplified.

Fixed-time attitude tracking control for spacecraft based on a fixed-time extended state observer
Science China Information Sciences, 2021This paper deals with the problem of fixed-time attitude tracking control for spacecraft subject to model uncertainties and external disturbances. Firstly, by using a fixed-time extended state observer (FxTESO), the synthetic uncertainties generated by external disturbances and model deviations can be estimated and compensated accordingly. We propose a

Command filtered fixed‐time control for a class of multi‐agent systems with sensor faults
International Journal of Robust and Nonlinear Control, 2021In this article, the command filtered fixed‐time fault‐tolerant control (FTC) problem is investigated for multi‐agent systems (MASs). The considered MASs with nonstrict feedback form are affected by unknown nonlinear functions and sensor faults, which ...
