摘要：
A security issue in the stability analysis problem is investigated for cyber-physical systems (CPSs) in this paper. A stability guaranteed self-triggered scheme is proposed to actively defend the denial-of-service (DoS) attacks and reduce unnecessary data communications in delta domain. In the self-triggered scheme, a predictive agent is designed, in which the stability of the CPS is considered. A transmit instant is confirmed based on the packets dropout caused by the DoS attacks and the time-varying delays in the communication channel. Furthermore, a sufficient condition in view of linear matrix inequalities (LMIs) is derived for stability of the CPS under DoS attacks. Numerical simulations are presented to illustrate the validity of the scheme.
