Resilient Event-Triggered Controller Synthesis of Networked Control Systems Under Periodic DoS Jamming Attacks

Area of Science:

• Control Systems Engineering
• Networked Systems
• Cybersecurity

Background:

• Networked control systems (NCS) face vulnerabilities from denial-of-service (DoS) attacks.
• Existing event-triggering communication schemes require robust designs against such threats.

Purpose of the Study:

• To develop a resilient event-triggering communication scheme (RETCS) for NCS under periodic DoS jamming attacks.
• To ensure system stability and controller performance despite partially known DoS attack characteristics.

Main Methods:

• Design of a new periodic RETCS considering power-constrained pulsewidth-modulated jammers.
• Construction of a state error-dependent switched system model incorporating RETCS and DoS attack impacts.
• Derivation of exponential stability criteria using piecewise Lyapunov functionals.

Main Results:

• Quantitative characterization of the relationship between DoS parameters, triggering parameters, sampling period, and decay rate.
• Development of a criterion for simultaneously obtaining triggering parameters and event-based state feedback controller gains.
• Validation of theoretical results through a satellite yaw-angle control system simulation.

Conclusions:

• The proposed RETCS effectively enhances NCS resilience against periodic DoS attacks.
• The derived stability criteria provide a systematic approach for designing robust event-triggered controllers.
• The study offers practical insights for securing NCS in adversarial communication environments.
