“…In this paper, we focus on distributed sensor and actuator reconfiguration in over-sensed and over-actuated networked control systems with a high degree of redundancy. In the event of malfunctioning actuators, sensors, or other system components, control systems may exhibit poor performances or even become unstable [2], [6]. Thus, the design of faulttolerant control systems is of major importance.…”

“…However, the vast majority of the solutions rely on a centralized approach [13], [14], [15], [16], [17]. Due to the increased complexity and size of current control systems, such techniques may be impractical [18], [6]. Through the increased computation and communication capabilities of embedded devices in these systems, FDD can technically move from a centralized implementation to a distributed one.…”

Abstract-In this paper, we address the problem of distributed reconfiguration of networked control systems upon the removal of misbehaving sensors and actuators. In particular, we consider systems with redundant sensors and actuators cooperating to recover from faults. Reconfiguration is performed while minimizing a steady-state estimation error covariance and a quadratic control cost. A model-matching condition is imposed on the reconfiguration scheme. It is shown that the reconfiguration and its underlying computation can be distributed. Using an average dwell-time approach, the stability of the distributed reconfiguration scheme under finite-time termination is analyzed. The approach is illustrated in a numerical example.

“…However, CPS may be deployed in very different scenarios: from small-scale applications to large-scale solutions [21]. Then, a deep analysis of device lifecycle and mobility in CPS should be based on the definition and characterization of several different deployments (manufacturing [7], irrigation [22], etc.…”

Cyber-Physical Systems (CPS) are often composed of a great number of mobile, wireless networked devices. In order to guarantee the system performing, management policies focused on becoming transparent to high-level applications, the changes in the hardware platform have to be implemented. However, traditional reactive methodologies and basic proposed predictive solutions are not valid either due to the extremely dynamical behavior of CPS or because the high number of involved devices prevents fulfill the timing requirements. Therefore, in this paper, we present an advance predictive solution for managing the mobility and device lifecycle, being able to meet all requirements of CPS. The solution is based on an infinite loop, which calculates, in each iteration, a sequence of future system states using a CPS simulator and interpolation algorithms. Furthermore, an experimental validation is provided in order to determine the performing of the proposed solution.

Cyber Physical Systems (CPSs) are increasingly being adopted in a wide range of industries such as smart power grids. Even though the rapid proliferation of CPSs brings huge benefits to our society, it also provides potential attackers with many new opportunities to affect the physical world such as disrupting the services controlled by CPSs. Stuxnet is an example of such an attack that was designed to interrupt the Iranian nuclear program. In this paper, we show how the vulnerabilities exploited by Stuxnet could have been addressed at the design level. We utilize a system theoretic approach, based on prior research on system safety, that takes both physical and cyber components into account to analyze the threats exploited by Stuxnet. We conclude that such an approach is capable of identifying cyber threats towards CPSs at the design level and provide practical recommendations that CPS designers can utilize to design a more secure CPS. Index TermsCPS security design, Stuxnet analysis, CPS, STAMP, Security and safety analysis.
