El presente trabajo se centra en la implementación de un sistema de control y ciberseguridad para una casa conectada a través de un PLC, empleando el software Home I/O, MATLAB y Machine Expert Basic. El objetivo principal es asegurar que el sistema de calefacción, gestionado mediante controladores PID, mantenga la temperatura de las habitaciones incluso bajo ataques de inyección de datos falsos. Se ha implementado un sistema neuroborroso (ANFIS) que, al recibir datos erróneos como temperaturas anómalas, es capaz de detectar si está siendo atacado. Además, ANFIS garantiza que el sistema siga funcionando de manera estable, ignorando los valores erróneos y tomando decisiones con base en los datos previos y el comportamiento del sistema. De este modo, se promueve una defensa robusta que permite continuar el control del entorno sin interrupciones, incluso bajo condiciones adversas.
This work focuses on the implementation of a control and cybersecurity system for a PLC-connected house, using Home I/O software, MATLAB and Machine Expert Basic. The main objective is to ensure that the heating system, managed by PID controllers, maintains the temperature of the rooms, even under false data injection attacks. A neuroborrous system (ANFIS) has been implemented which, upon receiving erroneous data such as anomalous temperatures, is able to check other variables of the system to detect if it is under attack. Furthermore, ANFIS ensures that the system continues to operate in a stable manner, ignoring erroneous values and making decisions based on previous data and system behaviour. This promotes a robust defence that allows control of the environment to continue without interruption, even under adverse conditions.
