Kalian D. Automation of the Process of Monitoring Quality Parameters of Digital Signal Synchronization Devices of Flexible Manufacturing System

The thesis is devoted to solving a scientific problem, which consists in the development of an automated system for monitoring quality indicators of digital signal synchronization devices, which consists of the software of the block of primary converters with a phase-locked loop subsystem of the reference generator frequency. In the dissertation work, for the first time were developed: a multichannel automated system for monitoring quality indicators of synchronization devices, adaptive digital phase discriminator, which provides the primary conversion of the time interval error into a digital signal, speed-optimal subsystem of phaselocked loop of the hierarchical structure; the boundary conditions were determined under which the periodicity of the phase discriminator characteristics does not affect the duration of the transient processes that are optimal in terms of speed, determining temperature instability of the duration of the transient process of the reference signal was formalized. The used tools were Simulink/MATLAB, Quartus Prime Lite Edition, Excel, Embarcadero RAD Studio. A study of an automated control system in the process of multi-product flexible manufacturing system of synchronization devices for various purposes was done.
