1993 IEEE International Solid-State Circuits Conference Digest of Technical Papers, 1993
The authors describe circuits and techniques that provide automatic on-chip impedance matching between a series-terminated, low-voltage swing, CMOS I/O pad, and an external interconnect. The automatic impedance control technique employs a digitally controlled output impedance driver, a high-gain, low-voltage differential receiver, and an IEEE-1149.1 ...

2019 IEEE International Conference on Advanced Robotics and its Social Impacts (ARSO), 2019
In impedance control, a robot is regulated to appear the port property similar to that of a physical system so that the wanted interactive performance is accomplished while interaction with the environment occurs. Since the port property of a robot is independent of the environment, impedance control can be synthesized without taking the environment ...

Impedance Control of Space Robot
International Journal of Modelling and Simulation, 2006The force control of a space robot is a difficult task, as the interaction of robot tip with the environment causes the base to change its position and orientation. Impedance control is an efficient method for trajectory and force control in a robotic system.

Tremor suppression through impedance control
IEEE Transactions on Rehabilitation Engineering, 2000This paper presents a method for designing tremor suppression systems that achieve a specified reduction in pathological tremor power through controlling the impedance of the human-machine interface. Position, rate, and acceleration feedback are examined and two techniques for the selection of feedback coefficients are discussed. Both techniques seek a

Force tracking in impedance control
[1993] Proceedings IEEE International Conference on Robotics and Automation, 1997This article presents two simple on-line schemes for force tracking within the impedance-control framework. The force- tracking capability of impedance control is particularly important for providing robustness in the presence of large uncertainties or variations in environmental parameters.

Passive impedance control with time-varying impedance center
Proceedings 2003 IEEE International Symposium on Computational Intelligence in Robotics and Automation. Computational Intelligence in Robotics and Automation for the New Millennium (Cat. No.03EX694), 2004Humans can perform skillful tasks adaptively and safely while interacting with uncertain dynamic environment. With respect to the adaptation ability, it was pointed out that impedance control could play a center role in the human motor control mechanism.

Learning control for impedance controlled manipulator
[1992] Proceedings of the 31st IEEE Conference on Decision and Control, 2005The authors propose a model-based learning control method for impedance controlled manipulators interacting with environments to perform accurate tracking of desired force and position trajectories. A Newton-like method is used to obtain the learning control law, which includes tracking errors and estimated parameters of environments such as viscous ...

This chapter is devoted to adaptive impedance matching techniques that have been investigated as a means to improve the link quality of mobile phones under fluctuating operating conditions. Adaptive techniques are attractive because they provide resilience to changes in body-effects and phone form factor.

Impedance-controlled ultrasound probe
SPIE Proceedings, 2011An actuated hand-held impedance-controlled ultrasound probe has been developed. The controller maintains a prescribed contact state (force and velocity) between the probe and a patient's body. The device will enhance the diagnostic capability of free-hand elastography and swept-force compound imaging, and also make it easier for a technician to ...

Casimir based impedance control
2012 IEEE International Conference on Robotics and Automation, 2012This paper proposes a new impedance control principle for mechanical systems which have driving systems whose control input is not the torque any more. It is shown how to transform such mechanical systems with driving systems into another systems with the desired mechanical impedance.
