Area of Science:

• Control Systems Engineering
• Networked Systems
• Cybersecurity

Background:

• Multiagent systems are crucial for distributed tasks but vulnerable to external disruptions.
• Denial-of-Service (DoS) attacks pose a significant threat to the stability and performance of networked systems.
• Achieving resilient synchronization in heterogeneous multiagent systems under cyberattacks is a complex challenge.

Purpose of the Study:

• To investigate the resilient output synchronization of linear heterogeneous multiagent systems under denial-of-service (DoS) attacks.
• To develop and analyze novel distributed control mechanisms for enhancing system robustness.
• To quantify the impact of aperiodic DoS attacks on system synchronization.

Main Methods:

• Design of distributed event-triggered and self-triggered control mechanisms.
• Utilization of local agent and neighbor information for control design.
• Analysis of system stability and synchronization performance under aperiodic DoS attacks.
• Mathematical formulation to reveal the relationship between DoS attack attributes and synchronization.

Main Results:

• Exponential output synchronization is achieved in the presence of aperiodic DoS attacks.
• The proposed event- and self-triggered control mechanisms effectively mitigate the impact of DoS attacks.
• A quantitative relationship between DoS attack characteristics and synchronization resilience is established.
• The distributed nature of the control mechanisms reduces communication overhead.

Conclusions:

• The developed control strategies ensure resilient output synchronization for linear heterogeneous multiagent systems facing DoS attacks.
• The findings provide a theoretical foundation and practical approach for securing networked systems against cyber threats.
• Simulation results validate the effectiveness and robustness of the proposed control mechanisms.
