Resilient Control Under Quantization and Denial-of-Service: Codesigning a Deadbeat Controller and Transmission Protocol

This article is concerned with the problem of stabilizing continuous-time linear time-invariant (LTI) systems subject to quantization and denial-of-service (DoS) attacks. In this context, two DoS-induced challenges emerge in design resilient encoding schemes, namely, coupling between strategies different signals, synchronization encoder decoder. These are addressed by a novel proposed structure based on deadbeat controller as well delicate transmission protocol for input output channels, codesigned leveraging controllability index. When both channels DoS attacks quantization, shown able decouple schemes input, output, estimated signals. property further corroborated designing conditions ensuring exponential stability closed-loop system. On other hand, when only channel network attack phenomena, can achieve stabilization without acknowledgment (ACK) contrast existing ACK-based results. Finally, numerical example given demonstrate practical merits theoretical approach.
