Abstract
The servo field is developing rapidly in all of its aspects. The methods presently used are based upon the theory of analytic functions and consist mainly of the study of the system subjected to steady sine-wave disturbances. Recently it has been proved that, in certain cases, it is possible to compute the system directly from statistical data concerning inputs (inputs composed of “orders” and “disturbances”). The paper first reviews the results that were obtained recently by the author in this field. A particular servocircuit is computed by statistical methods, and the output autocorrelation function of a relay also is obtained. Classical and statistical methods are then used in the analysis of a variable-inertia regulator. The principal properties of the variable-inertia regulator are derived for the cases where the inertia is controlled through an external source of power and where the inertia is self-adjusted by a passive network.
