AI Technical Summary

Technical Problem

In existing glass fiber surface desizing control systems, there is a lag in the spatiotemporal matching of energy supply and material heat demand, resulting in a lag in control power adjustment and affecting the consistency of the desizing process and energy efficiency.

Method used

Abstract

This invention relates to the field of industrial automation control technology and discloses a method for energy consumption balance control of glass fiber surface desizing based on dynamic modeling. The method includes: collecting real-time load data and temperature zone environmental parameters of the glass fiber desizing production line; calculating the theoretical desizing energy consumption and environmental heat loss to generate a basic power command; calculating the temperature zone dynamic hysteresis constant using a thermal inertial observer and superimposing it as a phase offset onto the basic power command to generate an initial power command sequence; extracting power boundary thresholds to verify the initial command amplitude; if there is an amplitude exceeding the limit, calling the power timing allocation logic to backfill the excess energy integral value to the preceding adjacent control cycle, generating a compensated power command sequence that meets physical boundary constraints and driving the heating output component. This invention maintains the spatiotemporal alignment of the control command center of gravity with load fluctuations, eliminates phase mismatch caused by thermal hysteresis, and ensures sufficient enthalpy change of the material.
