Аналіз динамічних властивостей тахометричних перетворювачів

Abstract

The problems of application of linear model of an asynchronous motor to the analysis of a measurement channel of an angular velocity of rotation are considered. The analytical expression for an angular velocity and dynamic moment, angular velocity on an output of the coupler is obtained. Represented, that the coupler essentially influences on an initial part of running, and error of quantization - in static mode of operation. The analytical expressions for a surge characteristic and transient period in the coupler are obtained. The algorithm of correction of a dynamic error of the coupler is offered. The equations for the basic metrology performances of a measurement channel of an angular velocity on the basis of digital frequence counter of instantaneous values are obtained.
