Abstract: |
Resilience,
i.e., the ability to withstand and recover from disruption, is a fundamental
requirement for mission-critical automation systems. Interconnection among
systems makes the analytical determination of resilience zones harder than in
isolated systems, because the failure of a system usually has an impact on
those connected to it. In this paper we propose an algorithm to determine
resilience zones of interconnected systems based on the computation of
piecewise linear Lyapunov functions. The algorithm
is based on a model introduced previously that abstracts from specific system
dynamics and enables analysis in the space of performances. Experiments with
an interconnected system inspired to a real wastewater treatment facility
show the feasibility and the accountability of our approach. |
