Analysis of a System for Automatic Control of the Process of Rewinding Filaments

Abstract

A system which ensures stabilization of filament velocity and tension has been developed to control the process of rewinding filaments. The main stage in the system’s operation is the matching of the velocities with the prescribed tension and diameter of the package. A PID controller serves as the main control element for fine adjustment of the system. To optimize the parameters of the PID controller, the dynamic characteristics of the filament rewinding process were determined by experimentally identifying recorded data on transients and then approximating them with transfer functions.
