Impact of stochasticity and time delay on stuxnet virus propagation in critical control systems

A complex computer worm that was first discovered in 2010, Stuxnet targeted industrial control systems and led to physical sabotage of production processes all without being detected. Symantec estimates that over 100,000 computers were infected by the malware, with around 60% of...

Adaptive Output Feedback Control with Prescribed-Time Performance for Nonlinear Cyber–Physical Systems Under Output Constraints, Actuator Backlash, and Malicious Attacks

This paper proposes an adaptive fuzzy prescribed-time output feedback control approach for strict-feedback nonlinear cyber–physical systems (CPSs) subjected to malicious attacks, output constraints, and backlash-like hysteresis. To approximate unknown system nonlinearities, fuzzy...
