The attacker capabilities are assumed limited in the sense that only a subset of all the sensors can be attacked although this subset is unknown. For a given upper bound on the number of attacked sensors, we propose a new selection strategy, which is able to achieve resiliency to attacks, using the width of estimated intervals. The interval observer is modelled as an impulsive system, where impulsive corrections are made periodically using measurement. The nonnegativity of the observation error between two successive measurements is preserved by applying the internal positivity of the system. The theoretical result is supported by numerical simulations.Show less >
