Abstract
In our ongoing research, we model the CPS subject to cyber-attacks as a hybrid system so that it can account for both the switching attack that tampers the discrete state dynamics (logical behavior) and the data injection attack which compromises the continuous state dynamics (physical behavior) of the CPS. Specifically, the identifiability and severity of the joint attacks are first analyzed, and a unified resilient hybrid control scheme is proposed to mitigate the impact of faults/attacks.
