In this article, our aim is to perform security threat assessment of networked control systems (NCS) systems with regulatory and supervisory control layers. We analyze the performance of a proportional-integral controller (regulatory layer), and a model-based diagnostic scheme (supervisory layer) under a class of deception attacks. We adopt a conservative approach by assuming that the attacker ...

The main objective of this study was to investigating the relation between organizational commitment and job satisfaction for accountants in 37 branches of the National Oil Refining & Distribution Company. In this research, it was used from the method stratified random sampling proportional to bulk, which questionnaires were distributed according to Morgan table and were distributed more than a...

Discrete event simulations for futuristic unmanned vehicle (UV) systems enable a cost and time effective methodology for evaluating various autonomy and humanautomation design parameters. Operator mental workload is an important factor to consider in such models. We present that the effects of operator workload on system performance can be modeled in such a simulation environment through a quan...

In this paper, a novel scheme of incorporating a learning mechanism into previous step supervisory controllers for adaptive fuzzy control is proposed to relax bounds required in the control process. In traditional supervisory adaptive fuzzy control approaches, the use of fuzzy estimators for approximating system functions and a robust supervisory control law are necessary to deal with any possi...
