Anticipatory synchronization with variable time delay and reset [PDF]

open access: yes, 2008
A method to synchronize two chaotic systems with anticipation or lag, coupled in the drive response mode, is proposed. The coupling involves variable delay with three time scales.

Fixed-time regulation of spacecraft orbit and attitude coordination with optimal actuation allocation using dual quaternion

open access: yesFrontiers in Robotics and AI, 2023
On-orbit service spacecraft with redundant actuators need to overcome orbital and attitude coupling when performing proximity maneuvers. In addition, transient/steady-state performance is required to fulfill the user-defined requirements.

Synchronization of Time-Varying Delayed Neural Networks by Fixed-Time Control

open access: yesIEEE 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.

Design of a Fixed-Time Stabilizer for Uncertain Chaotic Systems Subject to External Disturbances

open access: yesMathematics, 2023
This paper addresses the fixed-time stability problem of chaotic systems with internal uncertainties and external disturbances. To this end, new sliding-mode surfaces are introduced to design fixed-time controllers for the stabilization of perturbed ...

Simultaneous Identification of the Diffusion Coefficient and the Potential for the Schr\"odinger Operator with only one Observation

open access: yes, 2010
This article is devoted to prove a stability result for two independent coefficients for a Schr\"odinger operator in an unbounded strip. The result is obtained with only one observation on an unbounded subset of the boundary and the data of the solution ...

Stability of the bipartite matching model

open access: yes, 2010
We consider the bipartite matching model of customers and servers introduced by Caldentey, Kaplan, and Weiss (Adv. Appl. Probab., 2009). Customers and servers play symmetrical roles. There is a finite set C resp. S, of customer, resp.

Strichartz estimates in similarity coordinates and stable blowup for the critical wave equation

open access: yes, 2016
We establish Strichartz estimates in similarity coordinates for the radial wave equation in three spatial dimensions with a (time-dependent) self-similar potential.
