This article studies Lyapunov-like conditions to ensure a class of dynamical systems to
exhibit predefined-time stability. The origin of a dynamical system is predefined-time stable if …

In this paper, we provide a new nonconservative upper bound for the settling time of a class
of fixed‐time stable systems. To expose the value and the applicability of this result, we …

This paper investigates the attitude tracking problem of a rigid spacecraft using
contemporary predefined-time stability theory. To this end, the relative attitude kinematic and …

For vertical takeoff vertical landing (VTVL) reusable launch vehicle (RLV) with actuator faults
and saturation constraints, this paper presents a composite control system including a high …

This study investigates a new chattering-free robust predefined-time sliding mode control
(CFRPSMC) scheme for the trajectory tracking control problem of a three-degree-of-freedom …

Predefined-time stability contributes to constraining the tracking time of robotic manipulators,
but the stringent judgment conditions restrict its practical application. This paper studies an …

This manuscript introduces the design of a controller that ensures predefined-time
convergence for a class of second-order systems. In contrast to finite-and fixed-time …

This article proposes a multi-agent system with predefined-time consensus to solve
distributed optimization problem subject to inconsistent constraint sets. Under some derived …

In this article, the fixed‐time attitude tracking problem for rigid spacecraft is investigated
based on the adding‐a‐power‐integrator control technique. First, a fixed‐time attitude …

In this article, the attitude tracking problem for rigid spacecraft systems with the consideration
of actuator fault, input saturation, inertia uncertainties. and external disturbances is …
