Synchronic-In-Phase Electric Drive’s Characteristics Based on Multifunctional Logical Correlation Device with Indirect Angular Frequency Determination

Synchronic-in-phase electric drive is widely used in thermal-imaging and laser scanning systems due to high accuracy and dynamic characteristics in the wide range of angular speed regulation. The objective of the article is to analyse the dynamics improval of the electric drive with phase synchronization and synchronic-in-phase electric drive based on application of methods of angular speed errors’ indirect determination, which were implemented on the basis of multifunctional logical correlation device. The classification methods of indirect angular speed error’s determination (versions of frequency desynchronization of the comparable pulse sequences determination unit constructions) and the ways of the electric drive’s control organisation using the frequency desynchronization of the comparable pulse sequences determination unit were offered.
