Core Concepts
This paper proposes a decentralized time-regularized (Zeno-free) event-triggered control strategy for networked control systems subject to stochastic network delays and Poisson pulsing denial-of-service (Pp-DoS) attacks. The proposed approach ensures stochastic stability and Zeno-freeness of the closed-loop system by integrating the effects of stochastic delays and Pp-DoS attacks into the event-triggered control design.
Abstract
The paper considers a networked control system with multiple decentralized networks operating asynchronously and independently. The networks are subject to two sources of randomness: stochastic network delays and Poisson pulsing denial-of-service (Pp-DoS) attacks.
Key highlights:
A novel stochastic hybrid model is established to capture the dynamics of the networked control system under stochastic delays and Pp-DoS attacks.
Decentralized time-regularized (Zeno-free) event-triggered control strategies are designed to generate transmission instants for each network. The strategies are resilient to stochastic delays and Pp-DoS attacks.
The proposed approach ensures stochastic stability and Zeno-freeness of the closed-loop system by integrating the effects of stochastic delays and Pp-DoS attacks into the event-triggered control design.
The effectiveness of the proposed approach is demonstrated through the robust global attitude stabilization of flexible combined rotorcraft-like aerial vehicles.
