Dynamic survivability in oscillator systems

Whether the dynamic systems can display normal performance or complete key mission is the hot spot in recent years. In accordance with this, dynamic survivability is defined for the first time and mission-completion-probability is given as an index in this study. Taking the behavior of diffusively coupled oscillator systems with Erdös-Rényi random graph and Barabási-Albert scale-free network structures as examples, we show the network structures, systems’ parameters and attack strategies exhibit a profound influence on the dynamic survivability. Erdös-Rényi random graph and Barabási-Albert scale-free systems display better or worse dynamic survivability under different attack strategies respectively. Our outcomes fill the gap in the survivability study and are helpful for enhancing the dynamic survivability of real systems.
