.... Advanced force control in such interfaces can increase simulation fidelity through improvement of the transparency of the device. However, closed-loop force feedback is limited both due to the bandwidth limitations of force sensing and the associated cost of force sensors required for its implementation...

...Yutaka Uchimura; H. Kazerooni This paper deals with a system, which is subjected to very uncertain factors: human and environment. These independent uncertainties are dealt with explicitly on the framework of μ -synthesis. We also describe a controller design, which enables a robust force feedback...

...Katherine J. Kuchenbecker; Günter Niemeyer Telerobotic systems have persistently struggled to provide users with realistic force feedback; high-frequency contact transients convey important information about the remote environment but are typically attenuated to avoid the contact instability...

...Joshua P. Switkes; Eric J. Rossetter; Ian A. Coe; J. Christian Gerdes Lanekeeping assistance could save thousands of lives each year by maintaining lane position in the absence of driver steering commands. In order to work smoothly with the driver, handwheel force feedback must be an integral part...

... and experimentally demonstrates a teleoperation control algorithm that renders a hydraulic backhoe/force feedback joystick system as a two-port, coordinated, passive machine. By fully accounting for the fluid compressibility, inertia dynamics and nonlinearity, coordination performance is much improved over...

... is used to drive this error to zero, regardless of the source of the error. A semi-adaptive predictor that can distinguish between free space and a rigid contact environment is used to provide a more accurate force feedback on the master side. A full adaptive predictor is also used that estimates...

...M. A. Vitrani; J. Nikitczuk; G. Morel; C. Mavroidis; B. Weinberg Force-feedback mechanisms have been designed to simplify and enhance the human-vehicle interface. The increase in secondary controls within vehicle cockpits has created a desire for a simpler, more efficient human-vehicle interface...

...Pe´ter Korondi; Pe´ter T. Szemes; Hideki Hasimoto A high-performance human interface device needs accurate force feedback from the manipulated environment to the operator to improve the operation. The mechanism applied in the human interface device usually has a reasonable imminent friction...
