Finite-Time and Finite-Size Scaling of the Kuramoto Oscillators [PDF]

open access: yesPhysical Review Letters, 2014
Phase transition in its strict sense can only be observed in an infinite system, for which equilibration takes an infinitely long time at criticality. In numerical simulations, we are often limited both by the finiteness of the system size and by the finiteness of the observation time scale.

Global finite-time cooperative control for multiplemanipulators using integral sliding mode control [PDF]

open access: yes, 2022
In this paper, a global finite-time cooperative control is first time proposed for cooperative multiple manipulators. The proposed control scheme is developed based on an integration between a finite-time disturbance observer (FTDO) and a finite-time ...

Continuous Uniform Finite Time Stabilization of Planar Controllable Systems [PDF]

open access: yes, 2015
Continuous homogeneous controllers are utilized in a full state feedback setting for the uniform finite time stabilization of a perturbed double integrator in the presence of uniformly decaying piecewise continuous disturbances.

Finite Stopping Time and Finite Expected Stopping Time

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1965
Summary Generalized sequential probability-ratio procedures are defined for dependent and non-identically distributed random variables. For these procedures, conditions are found implying that the stopping time is finite with probability 1 and the expected stopping time is finite. These results are applied to rank order problems.

On Matrix Factorization and Scheduling for Finite-Time Average-Consensus [PDF]

open access: yes, 2010
We study the problem of communication scheduling for finite-time average-consensus in arbitrary connected networks. Viewing this consensus problem as a factorization of 1/n 11T by network-admissible families of matrices, we prove the existence of finite

Practical Adaptive Fast Terminal Sliding Mode Control for Servo Motors

open access: yesActuators, 2023
Position control of servo motor systems is a challenging task because of inevitable factors such as uncertainties, nonlinearities, parametric variations, and external perturbations.

Fast finite difference time domain analysis of microstrip patch antennas [PDF]

open access: yes, 1991
Although the finite-difference-time-domain method has been successfully used to model microstrip-fed patch antennas, this has been achieved using uniform grids.

Continuous Adaptive Finite Reaching Time Control and Second-Order Sliding modes [PDF]

open access: yes, 2013
This paper focuses on the design of adaptive finite reaching time control for first- and second-order dynamic systems with perturbation terms given in a regressive form. The uncertainties considered here are assumed to be bounded with unknown bounds. The

Distributed Finite-Time and Fixed-Time Nash Equilibrium Seeking for Non-Cooperative Game with Input Saturation

open access: yesMathematics, 2023
In this paper, a modified distributed Nash equilibrium seeking problem with input saturation has been investigated. The payoff function of each player is related to the communication topology, which is closer to the actual scenes. The sigmoid function is
