Cooperative Output-Feedback Secure Control of Distributed Linear Cyber-Physical Systems Resist Intermittent DoS Attacks

This article studies a cooperative output-feedback secure control problem for distributed cyber-physical systems over an unreliable communication interaction, which is to achieve coordination tracking in the presence of intermittent denial-of-service (DoS) attacks. Under switching network environment, first, method each subsystem proposed via neighborhood information, includes local state estimator and resilient controller. Second, based on topology-dependent Lyapunov function approach, design conditions protocol are derived such that errors uniformly ultimately bounded. Interestingly, by exploiting topology-allocation-dependent average dwell-time (TADADT) technique, stability analysis closed-loop error dynamics presented, can relax time constraints interaction topology switching. Finally, two numerical examples presented demonstrate effectiveness theoretical results.
