Diseño y simulación de un sistema de control colaborativo para una planta industrial textilera de vapor formada por cuatro etapas tres subprocesos industriales

Abstract

In the present work the simulation of a textile steam industrial plant formed by 4 stages and 3 industrial subprocesses is shown. Initially we proceed to develop the mathematical models of each stage, then we proceed to adapt these models to a real textile process. Controllers have been added to the water tanks, the water supply is delivered to the boilers by means of 3 centrifugal pumps with a specific operating sequence. In the cauldrons are implemented controllers by relationship, this controller is responsible for ensuring the correct relationship between air and fuel that is supplied to the boiler; They also have a water level controller inside. Once the controllers of each subprocess (cauldrons) are designed, disturbances are entered in them, observing the evident pressure drop, to solve it a collaborative control system is designed that makes the three subprocesses work together in such a way that they compensate for the disturbances produced in any cauldron. When the pressure drops or rises, the controller looks for which cauldron is failing and compensates it by distributing the pressure load equally among the remaining threads.
