Resilient control systems play a special role in the area
of cyber-physical systems, where the design must address the
question how complex dynamic plants are to be controlled safely
and reliably when a control system is under a cyber attack. In
this paper we describe a control theoretical framework based on
the concept of passivity for designing a control network which
can tolerate, for instance, denial-of-service attacks on networks
used in the closed loop. In particular, we demonstrate how the
resilient power junction structure could be applied, and provide
simulated results.
