Integration of modern defence weapons into ship power systems poses a challenge in terms of meeting the high ramp rate requirements of those loads. It might be demanding for the generators to meet the ramp rates of these loads. Failure to meet so, …
In recent years, DC and AC microgrid (MG) systems have attracted a major attention due to various potential for integration of future technology into conventional systems and control. The integration of such technology requires appropriate tools for …
This paper proposed a weighted L1 observer with prior pruning scheme against FDIAs. The pruning method gives a method to improve localization precision of any underlying localization algorithm withot training effort. Moreover, the weighted L1 observer with prior pruning is capable of coping with high-percentage of attacks among measurement nodes, which relaxes the transitional restriction on the maximum attack percentage for resilient L1 observer, thereby improve the resiliency of systems.
This paper proposes an approach to addresses the control challenges posed by a fault-induced uncertainty in both the dynamics and control input effectiveness of a class of hierarchical nonlinear systems in which the high-level dynamics is nonlinearly …
In this paper, an attack-resilient path tracking control scheme for wheeled mobile robot under an optimization-based FDIA was designed. The main contributions include; (1) Stable path-tracking control system for DDWMR, (2) Optimizationbased FDIA for DDWMR, and (3) The pruning-based observer design using UKF as the underlying observer. It was shown that the proposed pruning-based observer significantly improves the signal-to-attack ratio such that the UKF is able to resiliently estimate the state of the DDWMR even when portion of the sensor measurements were subject to an FDIA.
In this paper, we present the concept of boosting the resiliency of optimization-based observers for cyber-physical systems (CPS) using auxiliary sources of information. Due to the tight coupling of physics, communication and computation, a malicious …
Over the last decade, the number of cyberattacks targeting power systems and causing physical and economic damages has increased rapidly. Among them, False Data Injection Attacks (FDIAs) is a class of cyberattacks against power grid monitoring …
Cyberattacks against critical infrastructures, including power systems, are increasing rapidly. False Data Injection Attacks (FDIAs) are among the attacks that have been demonstrated to be effective and have been getting more attention over the last …
This paper considers the problem of optimal estimation for linear system with the measurement vector subject to arbitrary corruption by an adversarial agent. This problem is relevant to cyber-physical systems where, due to the tight coupling of …
This paper considers the problem of resiliency in the state estimation of a cyber-physical system when a portion of its sensor measurements contains malicious data added by an adversarial attacker. When the attack consists of arbitrary random …
