Some features of the organization of speed feedback in electric drives with microprocessor control.

Abstract

The issues of speed feedback organization are considered on the example of a microprocessor control system for an electric drive of a high-speed passenger elevator. The CSD, which excludes the accidental delay in the beginning of the speed code processing process relative to the moment of its readiness, as well as the organization of the controlling process using a similar DPS are given. Shown is a specific VDS interface with a minimum of hardware costs. Il 1. Bibliogr .: 4 titles.
