A history of control engineering, 1930-1955 by Stuart Bennett

By Stuart Bennett

Following his booklet at the starting place of regulate engineering (1800-1930 (see separate entry), the writer now lines improvement in the course of the serious interval 1930-1955, commonly pointed out because the interval of 'classical' regulate concept. within the Nineteen Thirties easy automated regulate units have been built and utilized in technique industries, as have been servos for the regulate of plane and ships and amplifiers for the phone approach and early desktops and so on. in the course of the battle many disparate rules have been introduced jointly for the improvement of plane monitoring and reaction platforms -- resulting in classical regulate thought which ruled the sector throughout the Fifties. the principles have been additionally being laid for the creation of what we now time period 'modern' keep an eye on theory.

Speculative Everything: Design, Fiction, and Social Dreaming

This day designers usually specialise in making know-how effortless to exploit, attractive, and consumable. In Speculative every little thing, Anthony Dunne and Fiona Raby suggest one of those layout that's used as a device to create not just issues yet principles. For them, layout is a way of speculating approximately how issues might be -- to visualize attainable futures.

Die Steuerung des Gaswechsels in schnellaufenden Verbrennungsmotoren: Konstruktion und Berechnung der Steuerelemente

Der Entwurf der Gassteuerung ist für den Motorenkonstrukteur eine besonders reizvolle Aufgabe. Wenn Hubraum, Zylinderzahl und Zylinderanordnung bei einem geplanten Motor festliegen, dann gibt es für das Triebwerk und die Zylinder­ konstruktion nicht allzu viele konstruktive Möglichkeiten, die Gassteuerung da­ gegen läßt dem Konstrukteur weiten Spielraum, hier kann er sein Können zeigen.

Example text

In 1905 the Cambridge Scientific Instrument Company introduced its Thread Recorder' based on this principle,10 and in 1915 the Bristol and Taylor companies introduced similar recorders. 11 Many users disliked the curved grid on the recording paper of deflection instruments (it was needed because the indicating arm necessarily swings in an arc) and for precise work preferred the more expensive potentiometric recorder. In potentiometric instruments some means has to be used to generate a voltage to match that of the thermocouple.

Meridith and Cooke, working at the Royal Aircraft Establishment, described in 1937 both the theoretical and practical developments that were taking place. The puzzle is the apparent lack of use of theoretical work. 56 It is also surprising that Melvill Jones (1935) in a major survey of aircraft stability and control did not cover feedback control. 20 Control technology in the 1930s W. 58 While both military and commercial secrecy may provide a reason for the slow spread of theoretical ideas, it is not the sole reason for aircraft builders eschewing dynamic stability calculations.
