Recent Developments in Speed Regulation

Transactions of the American Institute of Electrical Engineers, 1940
THE PROBLEM of automatically maintaining constancy of speed in rotating machinery is frequently encountered, aside from prime-mover governing, in such applications as d-c drives for a-c generators whose frequency must be kept unvarying to a high degree of accuracy for signalling purposes or for exacting test-floor operation.

Intuitiveness of vibrotactile speed regulation cues

ACM Transactions on Applied Perception, 2013
Interpretations of vibrotactile stimulations were compared between two participant groups. In both groups, the task was to evaluate specifically designed tactile stimulations presented to the wrist or chest. Ascending, constant, and descending vibration frequency profiles of the stimuli represented information for three different speed regulation ...

Research on speed regulation algorithm and fault detection of DC speed regulation system

2007 8th International Conference on Electronic Measurement and Instruments, 2007
This paper designs a speed-current dual close DC speed regulation system (SRS) and introduces the system's fault detection/protection strategy. The speed regulation (SR) algorithm is the core component of the SRS. By studying the SR principle and dynamic transfer function of SRS, adopting the flow of first interior last exterior loop, designs the SR ...

A five-component nanorotor with speed regulation

Chemical Communications, 2014
A five-component supramolecular nanorotor with reversibly acting brakes has been prepared from a four-component nanorotor by adding the photo- and heat-responsive 2,2'-diazastilbene as a signal transducer. The rotational speed was reversibly switched between 86 and 38 kHz.
