Diseño de un Controlador Difuso para el control de temperatura del módulo ET200SP usando el S7-1200

Abstract

Currently, there are various systems for the control of industrial processes related to variables such as temperature, level and pressure. Traditional Proportional Integral Derivative (PID) controllers have been replaced due to their limitations in the face of non-linear dynamics and inherent disturbances in complex thermal processes. In the industrial automation laboratory 1, the ET200SP module, using a PID controller for temperature regulation, needs to improve its efficiency for optimal operation and better practical understanding of fuzzy design. The S7-1200 series lacks a fuzzy logic controller for temperature control, which causes unwanted fluctuations and affects the efficiency of the process. Fuzzy controllers, which use rules based on expert knowledge, handle uncertainty and non-linearity in control systems better. The design of a fuzzy controller for the ET200SP module with the S7-1200 presents unique challenges, but it is essential to improve the performance of the system. The use of the S7-1200 is ideal for industrial automation due to its versatility and easy programming. The implementation of a fuzzy controller improves the management of the non-linear dynamics of the thermal system, providing more precise and adaptive adjustments according to the operating conditions. This work on the design of a fuzzy controller for temperature control of the ET200SP module with the S7-1200 is relevant due to the need for fuzzy controllers in temperature systems. The performance improvement not only optimizes the operation of the module, but also provides an advanced educational tool for Electronics and Automation students, promoting the use of modern control techniques and improving the understanding of complex systems.
