The time-delay control (TDC) has recently been spotlighted as an effective solution owing to model-free, efficient, and robust properties thanks to a time-delay estimation (TDE) technique. The gain of TDC, usually denoted by M̅, is crucial for its s

Objectives: To advance development of rehabilitation robots, the conditions to induce appropriate brain activation during rehabilitation performed by robots should be optimized, based on the concept of brain plasticity. In this study, we examined dif

A time delay estimation based general framework for trajectory tracking control of robot manipulators is presented. The controller consists of three elements: a time‐delay‐estimation element that cancels continuous nonlinearities of robot dynamic

Brain activation has been used to understand brain-level events associated with cognitive tasks or physical tasks. As a quantitative measure for brain activation, we propose entropy in place of signal amplitude and beta value, which are widely used,

Time delay control (TDC) is a promising technique for robot manipulators because it is model-free, efficient, and yet, robust. Nevertheless, when a robot operates under significant payload changes, it is difficult to achieve satisfactory performance

This paper proposes adaptive gain dynamics for time-delay control (TDC) of robot manipulators. The TDC is a widely employed approach for control of robot manipulators because it is model-independent, simple, and robust. Recently, however, it is repor

Robot Manipulators
Friction accounts for more than 60% of the motor torque, and hard nonlinearities due to Coulomb friction and stiction severely degrade control performances as they account for nearly 30% of the industrial robot motor torque. Although many friction co
