Os sistemas ciberfísicos (CPSs) assistidos por gêmeos digitais (DTs) integram loops de detecção e atuação em redes de comunicação em vários serviços e aplicações de infraestrutura. Este estudo apresenta uma visão geral do conceito, metodologia e aplicações da estimativa e controle integrado de qualidade de comunicação para CPSs assistidos por DT, tanto da perspectiva de comunicação quanto de controle. Os CPSs assistidos por DT podem ser considerados sistemas de controle em rede (NCSs) com modelos dinâmicos virtuais de entidades físicas. Um observador de estimativa de qualidade de comunicação (CQEO), que é uma versão estendida do observador de perturbação de comunicação (CDOB) utilizado para compensação de atraso em NCSs, é proposto para estimar os efeitos integrados da qualidade de serviços (QoS) e ataques cibernéticos no Aplicações NCS. Uma técnica de diversidade de caminhos com o CQEO também é proposta para obter NCSs confiáveis. A técnica proposta é aplicada a dois tipos de NCSs: controle remoto motor e sistemas de comunicação háptica. Além disso, os resultados da simulação num sistema de comunicação háptica mostram a eficácia da abordagem proposta. No final, são apresentadas futuras direções de pesquisa do esquema baseado em CQEO.

Abstract: Cyber-physical systems (CPSs) assisted by digital twins (DTs) integrate sensing-actuation loops over communication networks in various infrastructure services and applications. This study overviews the concept, methodology, and applications of the integrated communication quality estimation and control for the DT-assisted CPSs from both communications and control perspectives. The DT-assisted CPSs can be considered as networked control systems (NCSs) with virtual dynamic models of physical entities. A communication quality estimation observer (CQEO), which is an extended version of the communication disturbance observer (CDOB) utilized for time-delay compensation in NCSs, is proposed to estimate the integrated effects of the quality of services (QoS) and cyberattacks on the NCS applications. A path diversity technique with the CQEO is also proposed to achieve reliable NCSs. The proposed technique is applied to two kinds of NCSs: remote motor control and haptic communication systems. Moreover, results of the simulation on a haptic communication system show the effectiveness of the proposed approach. In the end, future research directions of the CQEO-based scheme are presented.
