Amplidyne circuit analysis

A method is shown for obtaining an analog of a typical amplidyne which has four control windings. Both the need for electronic analog differentiators and the possibility of circuits containing even-numbered amplifiers which give rise to unstable oscillations have been eliminated by the use of inverse inductances.1,2 This makes it possible to have each amplidyne parameter represented by a computer component, which makes for ease of analysis and synthesis. Nonlinearities may be included in the analog and the analysis can be as rigorous as desired, limited only by the number of analog computer elements available. The method presented is applicable to circuit or machine containing mutual reactances.
