Cyber-Physical Systems (CPS) applications are being increasingly used to provide services in domains such as health-care, transportation, and energy. Providing such services may require interactions between applications, some of which may be unpredictable. Understanding and mitigating such interactions require that CPSs be designed as open and composable systems. Composition has been studied extensively...
This paper considers the optimal management of an N source, DC microgrid with time-varying sources and loads. Optimality is defined as minimizing the amount of power lost through the boost converters that connect the N sources to the DC bus. The optimal power apportionment strategy is part of an overall grid management system that also includes control laws that manage bus voltage and boost currents...
The cyber security exposure of resilient systems is frequently described as an attack surface. A larger surface area indicates increased exposure to threats and a higher risk of compromise. Ad-hoc addition of dynamic proactive defenses to distributed systems may inadvertently increase the attack surface. This can lead to cyber friendly fire, a condition in which adding superfluous or incorrectly configured...
