Abstract

This paper will presents the mathematical model and improvement for winder system by adding the Proportional Intergral Derivative (PID) controller. Nowadays, winder system is commonly used as transporting system in production of textile, paper, metal, wire and more flexible material. Currently most of winder system using Programmable Logic Controller (PLC), tension observer controller, and others controller. The main goal of this project is to develop PID controller system into winder tension system to make the system more stable and consistent when running. Winder system move according to instruction given by PLC ladder diagram. In this paper, the PID gain parameters are tunned by heuristic aproach. The mathematical modeling of the system is established based on the tension control, speed of motor and other elements related to the system. Therefore, fabrication of lab-scale winder tension system that used in this project which is controlled by the MIDORI Green Pot Precision sensor using the PID algorithm system in PLC based system as the controller. The sensor relocated with the pendulum dancer and give the signal that control the speed of the motor based on the pendulum dancer. If the pendulum dancer moves upward, the sensor will give the signal to the PLC to speed up the speed of the motor. In PID system, the measurement that will be consider is proportional, integral and derivative. In this paper, Micro Box used to collect data from plant through MATLAB software. In experimental part, several experiment was done according to setup condition. Due to experimental results after implement PID, the optimum range for position of pendulum dancer is starting 60° to 85°. At the end of project give the results after implement PID controller, the system become more consistent and the problem of loosen of wire is overcome by that.
