چکیده

Der Betrieb komplexer, verteilter Regelungssysteme erfordert eine effiziente Nutzung vorhandener Ressourcen. Kürzlich erzielte Ergebnisse zeigen wesentliche Vorteile einer ereignisbasierten Regelung verglichen mit herkömmlichen Entwurfsmethoden mit periodischer Abtastung, wenn die Kommunikationsbandbreite, der Energieverbrauch oder die Rechenleistung beschränkt sind. Dieser Beitrag beschäftigt sich mit dem Entwurf ereignisbasierter Regelungen mehrerer heterogener Teilsysteme, deren Rückführschleifen über ein gemeinsames Kommunikationssystem verkoppelt sind. Mittels Zustandsaggregation wird eine dezentrale ereignisbasierte Regelungsstruktur entworfen und Stabilitätsbedinungen hergeleitet, unter welchen das Gesamtsystem stochastisch stabil ist. Unter diesen Stabilitätsbedingungen lässt sich zeigen, dass der vorgeschlagene Regelungsentwurf asymptotisch optimal mit zunehmender Anzahl an Teilsystemen ist.

Joint Design of Control and Communication in Wireless Networked Control Systems (Gemeinsamer Entwurf von Regelung und Kommunikation für funkbasierte Regelungssysteme)

The control performance of a wireless networked control system is a complex function of control structure, control system parameters e. g. sampling period, controller gain and communication system structure and parameters e. g. random delay, packet loss. Further limitations may arise from low energy low performance computing nodes. In order to predict or even optimize the control performance, a...

Suboptimal event-triggered control for networked control systems

The advent of networked control systems urges the digital control design to incorporate communication constraints efficiently. In order to accommodate this requirement, this article studies the joint design of controller and event-trigger for linear stochastic systems in the presence of a resource-limited communication channel which exhibits packet dropouts and time-delay. The event-trigger sit...

Modelling and Compensation of uncertain time-delays in networked control systems with plant uncertainty using an Improved RMPC Method

Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...
