Modeling, identification, and compensation of friction in harmonic drives

Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2003
Harmonic drives are increasingly used in precision positioning applications such as military radars, wafer handling machines, and satellite cameras. Precision tracking performance of these drives is deteriorated by nonlinear transmission attributes including kinematic error, flexibility, hysteresis and friction.

A new dynamic model of hysteresis in harmonic drives

IEEE Transactions on Industrial Electronics, 2003
In this paper, we propose a new dynamic model to describe the hysteresis phenomenon in harmonic drives. The experimental observation of the dynamic torque-displacement relationship for a harmonic drive shows a hysteresis characteristic indicating the simultaneous presence of energy storage and energy dissipation mechanisms.

Simulation of harmonic drive in precision robotic system

2010 Sixth International Conference on Natural Computation, 2010
A simulation model of precise harmonic drives transmission system including the effects of friction and transmission flexibility is developed in this paper. The friction in both motor and load side are analysed, nonlinear friction which include static, Coulomb and viscous friction are described as a function of position and velocity, the periodical ...

On the role of harmonics superimposed to the driving field in a harmonic generation process

The European Physical Journal D - Atomic, Molecular and Optical Physics, 2003
The spatially integrated emission of harmonics from two along the propagation axis spatially separated sources has been investigated as a function of the relative phase and relative emission power of the two sources. Temporal interference fringes have been observed with frequency distributions including multiples of the driving Ti:sapphire laser ...

Harmonizing clinical terminologies: driving interoperability in healthcare.

Studies in health technology and informatics, 2007
Internationally, there are countless initiatives to build National Healthcare Information Networks (NHIN) that electronically interconnect healthcare organizations by enhancing and integrating current information technology (IT) capabilities. The realization of such NHINs will enable the simple and immediate exchange of appropriate and vital clinical ...

Instrumented harmonic drives for robotic compliant maneuvers

Proceedings. 1991 IEEE International Conference on Robotics and Automation, 2002
The dynamic behaviour of a harmonic drive, in particular the non-backdrivability, is developed in terms of a sensitivity transfer function (or 1/impedance). The instrumentation of the harmonic drive with torque sensor is described. This leads to a description of the control algorithm which allows modulation of the sensitivity transfer function within ...

The Cloud Drives Harmonization and Standardization

2016
IT islands—they rise up from the flood of data in every corporation and every medium-sized company. As sunny as they may sound, they cast a long shadow over a company’s flexibility. In this dynamic age of digital transformation, effective administration is wrecked on the shores of these islands. In reality there are often local databases, each of which

Drives with harmonic gears for servo systems

Russian Engineering Research, 2016
Various drives with harmonic gear systems and generators of internal and external deformation waves are considered. A method of designing harmonic gear systems on the basis of dialog-based interactive software is outlined. A systems approach to the design of electromechanical servo-system drives improves the design quality and reduces the design time.
