Controller design based on networked control system (NCS) framework combines sensing, control, and actuation tasks using shared channel of communication network. Such a use of communication channel often makes the NCS design more challenging due to the presence of system uncertainties, limitation on available computational/communication systems resources, as well as possible occurrences of data transmission failures or cyber attacks. This paper develops mathematical grounds for dynamic event-triggered control design method for an uncertain linear NCS with matched uncertainties whose communication channel undergoes cyber attacks in the form of Denial-of-Service (DoS). The DoS attacks are assumed to halt the execution of control update tasks that was scheduled by the dynamic event-triggered control scheme. Under such possible occurrences of DoS attacks, this paper bounds the allowable duration of the DoS presence and derives suitable control signals which can guarantee the closed loop NCS remains stable.

This paper presents mathematical foundations for a dynamic event-triggered scheme (DETS) designed for uncertain linear networked control systems (NCS) subjected to Denial-of-Service (DoS) attacks.The study focuses on matched uncertainty and models DoS attacks as interruptions to control updates.The research derives control signals and update schemes that ensure the stability of the closed-loop NCS even in the presence of DoS attacks, providing a measure of the NCS resiliency to such attacks.

Penelitian lebih lanjut dapat dilakukan untuk menguji efektivitas skema kontrol yang diusulkan pada sistem NCS yang lebih kompleks dan realistis, termasuk mempertimbangkan berbagai jenis serangan siber selain DoS. Selain itu, eksplorasi metode adaptif untuk memperkirakan dan mengkompensasi ketidakpastian sistem secara *online* dapat meningkatkan ketahanan NCS terhadap gangguan yang tidak terduga. Terakhir, pengembangan strategi kontrol terdistribusi yang memanfaatkan redundansi dalam jaringan NCS dapat meningkatkan keandalan dan ketahanan sistem secara keseluruhan, terutama dalam menghadapi serangan yang terkoordinasi.
