We review the main design techniques of state observer design for continuous-time
dynamical systems, namely algorithms which reconstruct online the full information of a …

This paper studies the problem of the prescribed-time tracking control for a class of strict-
feedback nonlinear systems with guaranteed performance. We will design a controller to …

This article presents a fixed-time observer-based safety control strategy for quadrotor
unmanned aerial vehicles (UAVs) against multiple actuator faults and unknown …

Most current methodologies on fixed-time adaptive fuzzy control for uncertain nonlinear
systems result in practical fixed-time stability but not fixed-time stability, or require prior …

We propose a family of smooth explicit Lyapunov functions (LF) for Levant's differentiator,
which is a discontinuous real-time robust and exact differentiator. These LF allow the …

This paper considers the problem of fuzzy logic adaptive fixed-time control for nonlinear
switched system. Different from existing research results on fixed-time control, the system …

This article is aimed at develo** a finite-time adaptive fuzzy control strategy for a class of
nonlinear strict-feedback systems. For the first time, a fast finite-time practical stability criteria …

In this paper the prescribed-time output feedback stabilization of linear systems is addressed
using both a functional observer, which includes the reduced-order observer as a special …

The calculation of available wrench set of tethered multi-rotor UAVs is more challenging
than that of the traditional cable-driven parallel robots (CDPRs) with fixed anchor points, due …

Uncertainty and measurement noise are main obstacles that limit the tracking control
performances of flexible air-breathing hypersonic vehicles (FAHVs). In this article, we …
