Abstract

Due to the wide application of cyber-physical systems (CPSs) into society, sophisticated cyber-attacks on the physical plants have recently become a topic of scientific research. In this article, the issue of designing stealthy sparse attacks is considered for CPSs which aim to realize simultaneous actuator and sensor attacks. First, sensor and actuator attacks that satisfy sparse and stealthy conditions using input-output information are designed with the aid of subspace identification techniques. Then, an attack impact index is proposed to assess the degradation caused to the system performance, which provide reference for the design of the most destructive sparse attack mode. Finally, two numerical examples are provided to verify the effectiveness of proposed methods.
