control of a Teleoperation Drive-by-Wire System with Communication Time-Delay
2006 Edition, June 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

An Halpha approach to robust control of bilateral teleoperation systems under communication time-delay is considered and applied on an experimental setup. Using a small gain approach an Halpha controller is first designed in the nominal case...

H/sub 2/ optimal controller design for micro-teleoperation with delay
2004 Edition, Volume 1, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This study aims to develop a force-reflecting macromicro teleoperator with different scaled worlds. A bilateral control system for scaled teleoperation provides the human operator with a feel of the task at the micro-scale. However,...

2015 Edition, September 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents system framework and control algorithm for a human operator to remotely teleoperate a group of mobile robots over a network with time-varying delays. By utilizing the task-space technique adopted from...

Passive teleoperation control with varying time delay
2006 Edition, January 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper is devoted to the passivity based control in force reflecting bilateral teleoperation for varying time communication delay. In order to improve the stability and task performance, master and slave in bilateral teleoperation must be coupled...

A Relaxed CQ Algorithm for Solving Split Feasibility Problem
2011 Edition, July 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The split feasibility problem(SFP) is to find a point x ∈ C such that Ax ∈ Q, where A, H/sub 1/ → H/sub 2/ is a bounded linear operator, and C and Q be nonempty closed convex subset of Hilbert space H/sub 1/ and...

A system for high precision glass-to-glass delay measurements in video communication
2016 Edition, September 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Ultra low delay video transmission is becoming increasingly important. Video-based applications with ultra low delay requirements range from teleoperation scenarios such as controlling drones or telesurgery to autonomous control of dynamic processes...

The fractal structure of cardiovascular beat-to-beat series described over a broad range of scales: Differences between blood pressure and heart rate, and the effect of gender
2015 Edition, August 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The fractal characteristics of heart rate variability are usually assessed by estimating short- and long-term scale coefficients, α<;sub>1<;/sub>and α<;sub>2<;/sub>, by detrended fluctuation analysis. Recently we extended this approach...

Time Delay Compensation in Bilateral Teleoperation Systems
2006 Edition, July 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Time delay in bilateral teleoperation systems is inevitable and very serious problem. It possibly destabilize systems and deteriorates the performance of systems. Many researches about time delay in bilateral teleoperation...

Stable and transparent teleoperation over communication time-delay: Observer-based input-to-state stable approach
2016 Edition, April 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, an observer-based input-to-state stable approach is proposed to stabilize teleoperation systems over communication time-delay with better transparency compared with passivity approaches. In this paper, input-to-state stable approach is...

Stability analysis of teleoperation system by state convergence with variable time delay
2013 Edition, June 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose a novel control scheme for bilateral teleoperation of n degree-of-freedom (DOF) nonlinear robotic systems with time-varying communication delay. A major contribution from this work lies in the demonstration that...
