This article is concerned with the problem of fixed-time (FXT) and preassigned-time (PAT)
synchronization for discontinuous dynamic networks by improving FXT stability and …

Fixed-time stability (FXTS) and fixed-time control (FXTC) of dynamic systems are
reconsidered in this article based on special functions from the view of improving the …

Recently, there has been a great deal of attention in a class of finite‐time stable dynamical
systems, called fixed‐time stable, that exhibit uniform convergence with respect to its initial …

This work investigates the problem of fast tracking control for a class of high-order nonlinear
systems subject to the matched disturbances. More particularly, a novel practical fixed-time …

This work addresses the predefined-time convergence problem for a class of second order
nonlinear systems subjected to matched disturbances. A novel family of sigmoid function …

This paper aims to provide a methodology for generating autonomous and non-autonomous
systems with a fixed-time stable equilibrium point where an Upper Bound of the Settling …

Recently, a first‐order differentiator based on time‐varying gains was introduced in the
literature, in its nonrecursive form, for signals having a second‐order derivative bounded by …

This article addresses the distributed prescribed-time leader-following consensus problem
for a class of high-order multi-agent systems (MASs) with perturbed nonlinear agents …

This paper presents a unified Lyapunov-based predefined-time stability theorem that
includes three sufficient conditions. The standard theoretical analysis method for achieving …

This paper investigates consensus tracking control for nonlinear multi-agent systems with
unknown disturbances. By introducing an auxiliary dynamic system, a fixed-time sliding …
