Sažetak
The paper elaborates a cyber-attack on a control system that is realized as a distortion of its feedback signal. The control system has an implemented detection of this type of cyber- attack by means of a minimum robust positively invariant set computed for the closed-loop control system for the case of bounded measurement noise. The work explores how to maximize the damage to the control system from the side of a well- informed attacker that tries to remain non- discovered by the implemented detection system. The information obtained through this analysis is crucial to assess the effectiveness of the analyzed detection system in suppressing potential damages of the considered cyber-attack type. It gives an insight into how large the damage can be in the worst case with the implemented protection scheme. A demonstration is performed on a simple double- integrator process and an important conclusion is that even the fully- informed attacker cannot perform significant damage while remaining below the radar of the invariant-set- based cyber-threat detection.
