A Preliminary Study of Disturbance Absorbing Controllers for Servomechanism Problems.
Abstract
Controllers for servomechanism problems are ordinarily designed under the unrealistic assumption that no external disturbances are acting on the plant. Such controllers may fail to meet performance specifications when the plant is, in fact, subjected to persistently acting external disturbances. In this study, the author's recently developed theory of disturbance absorbing controllers is extended to include a special class of servomechanism controllers. The result is a new variety of servomechanism controller which can maintain high accuracy servo-tracking in the face of a broad class of unknown, unmeasurable, persistently acting external plant disturbances. The extension of these results to cover a more general class of servomechanism problems will be investigated in a future study. (Author)
