Sistem siber-fizikal (CPS) dibantu oleh kembar digital (DT) menyepadukan gelung penggerak penderiaan ke atas rangkaian komunikasi dalam pelbagai perkhidmatan dan aplikasi infrastruktur. Kajian ini meninjau konsep, metodologi dan aplikasi anggaran kualiti komunikasi bersepadu dan kawalan untuk CPS dibantu DT dari kedua-dua perspektif komunikasi dan kawalan. CPS dibantu DT boleh dianggap sebagai sistem kawalan rangkaian (NCS) dengan model dinamik maya entiti fizikal. Pemerhati anggaran kualiti komunikasi (CQEO), yang merupakan versi lanjutan pemerhati gangguan komunikasi (CDOB) yang digunakan untuk pampasan kelewatan masa dalam NCS, dicadangkan untuk menganggarkan kesan bersepadu kualiti perkhidmatan (QoS) dan serangan siber terhadap aplikasi NCS. Teknik kepelbagaian laluan dengan CQEO juga dicadangkan untuk mencapai NCS yang boleh dipercayai. Teknik yang dicadangkan digunakan untuk dua jenis NCS: kawalan motor jauh dan sistem komunikasi haptik. Selain itu, hasil simulasi pada sistem komunikasi haptik menunjukkan keberkesanan pendekatan yang dicadangkan. Pada akhirnya, hala tuju penyelidikan masa depan skim berasaskan CQEO dibentangkan.

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.
