Summary
Passivity and dissipativity are important in the study of Cyber Physical Systems (CPS) where systems with time and event-driven dynamics are connected. This paper provides conditions which guarantee stability of interconnected switched systems which may be used to model CPS. Results are presented for maintaining stability when switched systems are connected in feedback. Then methods for maintaining stability of passive switched systems that are connected over a network with delays are presented.
Zusammenfassung
Passivität und Dissipativität sind wichtige bei der Untersuchung von Cyber-physischen Systemen (CPS), die typischerweise aus zeit- und ereignisgesteuerter Dynamik bestehen. Dieser Beitrag stellt Bedingungen die die Stabilität vernetzter schaltender Systeme garantieren, die zur Modellierung von CPS verwendet werden können. Es werden Ergebnisse präsentiert, um Stabilität sicherzustellen, wenn Systeme über eine Rückführung miteinander verbunden werden. Außerdem Methoden zur Sicherstellung der Stabilität von geschalteten Systemen, die über ein Netzwerk mit Totzeiten verbunden sind, behandelt.
