Observadores Distribuidos Garantistas para Sistemas en Red

Ramón A. García, Francisco R. Rubio, Luis Orihuela, Pablo Millán, Manuel G. Ortega

Resumen

En este artículo se propone un observador distribuido garantista para sistemas en red, considerando de forma explícita el problema de los retardos variables en las comunicaciones. Se asume que la información intercambiada entre agentes llega siempre a su destino, si bien las comunicaciones están sujetas a retardos variables, cuyo valor máximo se supone conocido. Cada observador trabaja con información parcial, y necesita comunicarse con observadores vecinos para llevar a cabo una estimación del estado completo del sistema. Para representar a los conjuntos garantistas, cuya función es acotar en tiempo real la región en la que se encuentra el estado del sistema, se ha optado por la utilización de zonotopos. Esto permite integrar de forma sencilla la información recibida por cada agente. Finalmente se presentan resultados de simulación para validar el algoritmo propuesto.

Palabras clave
