Harmonic analysis of slip-power recovery drives

IEEE Transactions on Industry Applications, 1992
A method of evaluating harmonic currents and voltages associated with slip power recovery drives is presented. The rectifier commutation overlap and DC link current ripple are included in the analysis by using a hybrid between the traditional d-q and a-b-c induction motor models. The harmonic components are determined from closed-form expressions which

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.

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

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 ...
