Modelación, programación y simulación del control automático mediante plc para sistemas industriales : modelación, programación y simulación del control automático mediante PLC de una cámara frigorífica industrial.

Abstract

The following curricular integration work focuses on the modeling, programming, and simulation of the automatic control of an industrial refrigeration chamber using a Programmable Logic Controller (PLC), whose main objective is to optimize the operation of the refrigeration chamber, ensuring the proper preservation of the stored products. The first step is the modeling of the refrigeration chamber. Variables such as temperature, humidity, and air flow are considered. Next, the PLC is programmed. Specific programming languages for PLCs, such as Ladder or Structured Text, are used to implement control algorithms that regulate the modeled variables. Simulation allows the system’s operation to be validated before its real implementation, for this, simulation software is used that allows recreating the behavior of the refrigeration chamber and the PLC. In this way, possible failures in the modeling and programming stages can be detected and corrected. The PLC will be in charge of regulating the chamber’s variables according to the programmed control algorithms, thus ensuring the optimal operation of the refrigeration chamber. In this way, the importance of integrating modeling, programming, and simulation in the automatic control of industrial systems is demonstrated, and how this integration can lead to the optimization of industrial processes.
