Constraining Attacker Capabilities Through Actuator Saturation [PDF]

2018 Annual American Control Conference (ACC), 2017
For LTI control systems, we provide mathematical tools - in terms of Linear Matrix Inequalities - for computing outer ellipsoidal bounds on the reachable sets that attacks can induce in the system when they are subject to the physical limits of the ...
