Estimación y Control Distribuidos de Sistemas sobre Redes de Comunicación

Francisco R. Rubio, Pablo Millán, Luis Orihuela, Carlos Vivas

Resumen

Este trabajo presenta una técnica de diseño novedosa para la estimación y control distribuido de sistemas en red. Se considera un proceso discreto de gran escala controlado por una red de agentes que pueden recopilar información acerca de la evolución de la planta y aplicar las acciones de control para mejorar su comportamiento. El diseño propuesto es de especial interés cuando no se tiene observabilidad/controlabilidad local, de forma que es necesario utilizar la comunicación entre agentes para tener suficiente información dinámica del sistema. El objetivo global es diseñar un esquema de control y estimación distribuida, de forma que se obtengan estimaciones fiables por parte de los agentes así como un desempeño de control adecuado. El trabajo analiza dos esquemas diferentes de comunicación entre agentes, muestreo periódico y basado en eventos, proporcionando pruebas de estabilidad utilizando el criterio de Lyapunov y métodos de diseño en términos de desigualdades matriciales lineales LMIs (del inglés, Linear Matrix Inequalities). Se muestran resultados experimentales sobre un sistema de cuatro tanques para demostrar la eficacia de las metodologías propuestas.
