N2 - This paper investigates event-triggered model predictive security control (MPSC) for switched systems under dual-channel denial of service (DoS) attacks. By considering the communication threat caused by DoS attacks, a structure including network control loop and local control loop is implemented to ensure network transmission security. A permissible type-switching strategy is proposed to coordinate the work sequence of optimized controllers (network) and guaranteed controllers (local). To save limited network resources and reduce the impacts of data-packet loss caused by DoS attacks, resilient dual-adaptive event-triggering schemes (RDESs) are proposed. Then, a novel closed-loop switched system modeling method with dual-channel delays and attacks is presented. In such a framework, the control performance may fluctuate the permissible threshold, causing the frequent switching phenomenon between network and local controllers. A stay-time-based permissible type-switching strategy (SPTS) is designed to deal with this. Then, a set of sufficient conditions is given to guarantee stability. Finally, numerical examples are given to illustrate the effectiveness of the proposed method.
