Cyberattack and Fault Detection and Isolation in Cyber-Physical Systems
Investigation of stealthy deception cyberattacks in cyber-physical systems, including zero-dynamics, controllable, and covert attacks, and the development of dynamic coding–based defenses with provable detectability guarantees.
Closing the Loop Inside Neural Networks: Causality-Guided Layer Adaptation for Fault Recovery Control
A causality-guided neural control framework for actuator fault recovery, combining offline causal inference with selective online adaptation under Lyapunov stability guarantees.
