Improving dynamics of synchronously-inphase electric drive in transient synchronization and phasing modes

Abstract

The synchronously-inphase electric drive built on the basis of electric drive with phase synchronization is widely used in thermal imaging and laser scanning systems due to the high accuracy and dynamic characteristics in a wide range of adjustment of the angular velocity. The purpose of the article is to develop ways to control a synchronous-in-phase electric drive in synchronization and phasing modes, which allow to improve the dynamic performance of the electric drive. The method of quasi-optimal speed phasing of electric drive is improved. Recommendations on the organization of transient processes with an abrupt change in the reference signal are formulated. The authors propose circuit implementations of a pulse frequency-phase discriminator with an extended linear zone in the phase comparison mode, which allow to improve the dynamics of the electric drive in the synchronization mode.
