Dynamic Logarithmic Quantized Stabilization of Switched Systems Subject to Denial-of-Service Attacks

The problem of the dynamic quantization stabilization of the networked switched systems affected by denial-of-service (DoS) attacks is investigated. Firstly, a quasi-periodic logarithmic quantization strategy is proposed, which ensures the quantization accuracy of the quantizer under the premise of limited quantization levels. Secondly, the adjustment time and the update period of the quantizer are designed to avoid the saturation of the quantizer under DoS attacks. Subsequently, a quantized feedback controller is designed for the switched system under the influence of DoS attacks, and the sufficient conditions are obtained to ensure the global asymptotic stability of the closed-loop system. Finally, the effectiveness of the theoretical analysis is verified through a dual-tank system.
