Secure control for the discrete-time CPSs under DoS attacks via a switching strategy

In this work, the stability analysis and stabilization problem for one class of discrete-time cyber-physical systems (CPSs) under denial-of-service (DoS) attacks is investigated. Firstly, according to appropriate formulation of DoS attacks, different scenarios based on the presence or absence of DoS attacks are developed. Then the input-to-state stability (ISS) and globally asymptotical stability (GAS) of the considered CPSs can be guaranteed in terms of DoS frequency and duration restrictions, respectively. Finally, one example is given to verify the applicability of our theoretical result.
