Recent Developments in Speed Regulation
Transactions of the American Institute of Electrical Engineers, 1940THE 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.

Research on speed regulation algorithm and fault detection of DC speed regulation system
2007 8th International Conference on Electronic Measurement and Instruments, 2007This 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, 2014A 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.

Intuitiveness of vibrotactile speed regulation cues
ACM Transactions on Applied Perception, 2013Interpretations 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 ...

Electrical Engineering, 1931
Automatic regulators to be suitable for industrial use must be quick in response, sturdy in construction, require a minimum of maintenance, and be adaptable to a wide variety of applications. How one of the newer types of carbon-pile regulators meets these exacting requirements is outlined in some detail.

Speed regulation by digital methods
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1961By application of digital techniques to a speed-regulating system, it is possible to regulate the controlled variable to accuracies not attainable by other methods. The development of a typical system is described The development of digital technology over the past 20 years has opened the way to vast new areas of industrial uses.

Regulator Characteristics: A Conparision of Two Speed Regulations
IEEE Transactions on Industry and General Applications, 1971The importance of the transient characteristics of analog regulators used on paper machine drives is shown. The speed regulator was chosen as a model since it is the regulator that is most often used. Two different forms of speed regulators were used to demonstrate the differences between different forms of regulators with comments on these differences.

Idling speed regulator of automobile
Proceedings of 2011 International Conference on Electronics and Optoelectronics, 2011The functions of idling speed regulator are very important. It can stabilize engine's idling speed, which can reduce the oil consumption when automobile is moving with idling speed. This can prevent automobile engine miss. And idling speed could be regulated by controlling throttle valve by-pass style.

Tension and Speed Regulation of Axially Moving Materials
Volume 6: International Symposium on Motion and Vibration Control, 1999Abstract In this paper, the tension and speed of an axially moving material system are regulated using control torques applied to rollers at each end of a controlled span. Given a distributed parameter model, Lyapunov-type arguments produce a model-based boundary control law that exponentially stabilizes the material tension and speed at
