Enhancing Robot End‐Effector Trajectory Tracking Using Virtual Force‐Tracking Impedance Control

Advanced Intelligent Systems, Volume 7, Issue 2, February 2025.
This article introduces an extended Cartesian space robot control framework using virtual force‐tracking impedance control to improve end‐effector trajectory tracking. An assumed virtual surface near the desired trajectory generates a contact force, which is controlled by an impedance model to maintain a constant desired force.

Attack detection method for encrypted wave‐variable‐based bilateral control systems

IET Control Theory &Applications, Volume 18, Issue 11, Page 1461-1474, July 2024.
This study presents an energy‐based attack detection method involving an encrypted bilateral control system using wave variables. This study provides a specific design for reasonable threshold parameters concerning the energy of the control system. The theorem and the experimental validation confirm that the developed encrypted wave‐variable‐based ...

A Review of Bilateral Teleoperation Algorithms

Acta Polytechnica Hungarica, 2016
Bilateral Teleoperation is a key technology to allow humans to interact with remote environments by providing the operator with haptic feedback. Haptic feedback from the one hand improves human perception and therefore the quality of the human-robot interaction, on the other hand it can tamper with the stability of the system when the communication ...

Minimal operation region prediction for networked control robotic manipulators subject to time‐varying delays and disturbances

IET Control Theory &Applications, Volume 18, Issue 8, Page 1085-1097, May 2024.
This study investigates the nonlinear problem of predicting minimal operation regions of robotic arms subject to time‐varying delays, uncertainties and disturbances. The proposed method solving the nonlinear problem is formulated as an Linear Matrix Inequality optimisation problem, and is able to establish minimal reachable bounding sets of the ...
