A Basic Study on the constant Tension control with variable PID as a function of inertia moment in the winding roll System

면취기 시스템에 있어서 부하의 관성모멘트에 따른 가변 PID 일정 장력제어의 기초연구

In the winding system, the constant tension control is too important. In this study, we've used a variable PID system as a function of a radius of winding roll. As a result, it was possible to measure a winding roll radius in the real time by making a mathematical model for measuring a winding roll radius. Finally, we've compared PID parameters as a function of winding roll radius after getting PID parameters in terms of the Ziegler & Nichols(ZN) method.
