Diseño e implementación de un sistema de control a lazo cerrado PID para manipular la temperatura en el proceso de termoformado

Abstract

The purpose of this work lies in the design and implementation of a closed-circuit temperature control system (SCTLC), to control the temperature transfer in the mold of the thermoprepared system, where the blocks are manufactured from multilayer containers. post-consumer. The plant (electrical resistance) was characterized, with the AC voltage levels (30V, 60V, 90V and 120V) in a time of 60 min each of the voltage levels, considering the initial temperature (ambient temperature), in function of the step signal, then, the plant model was determined using Matlab software and the analytical method with the data of the plant characteristic curve at a voltage of 120Vac, obtaining the first-order transfer function, then The PID controller implemented the Ziegler & Nichols method and the Matlab software were tuned and finally the reference input, the control, the power stage, the plant and the feedback were coupled. This project contributes to control and stabilize the resistance temperature, implemented in the thermoforming process, for the production of blocks using multilayer containers.

“…Control automático programado: En este tipo de control, no interviene directamente el operador, en donde el sistema pre-programado, realiza todas las labores del control automático, pero su solución es programada, sin embargo, se puede modificar su proceso de operación o ley de control [14].…”
