As an important supplement, the microgrid (MG) plays a complementary role in improving the power supply quality. However, the addition of the MG increases the complexity, and how to balance the interests of the participants has become a substaintial problem. Based on the analysis of the power consumption characteristics of rural residential, agricultural and industrial areas, a game relationship model between MG operators and power users is established, and the overall optimal strategy is obtained in this paper. For consumers, it can effectively achieve the effect of ‘peak shaving and valley filling’ and reduce the cost of electricity. For MG operators, it can improve the consumption rate of renewable energy and increase revenue.","PeriodicalId":37058,"journal":{"name":"Cyber-Physical Systems","volume":"18 1","pages":"122 - 143"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89252280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, this paper presents a Protected Cluster-assisted SDWSN for Edge-IoT (ProSD-EdgeIoT) architecture.

The scheduling of network access time to multi-domain data in an industrial hybrid network is a challenging task. This paper extends the contribution of the network model mentioned in the literature to assess the bandwidth of both the scheduled and unscheduled communication in hybrid networked control systems. This paper's contribution includes four phases as follows: a) simulation of a hybrid networked control system (h-NCS) consists of four domains with different bandwidth allocations for an application of transmitting a data packet over a network stack from wired node to the wireless node. b) the mathematical demonstration of TCP and IEEE802.11b related to domains incorporated in h-NCS for data transmission. c) the normalisation of the bandwidth of the network access time for both scheduled and unscheduled data packets of h-NCS by implementing Dempster’s rule of combination. d) comparison analysis of proposed h-NCS with the traditional NCS for network access time utilised by both the scheduled and unscheduled data transmission.","PeriodicalId":37058,"journal":{"name":"Cyber-Physical Systems","volume":"35 1","pages":"321 - 346"},"PeriodicalIF":0.0,"publicationDate":"2021-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78336831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the complexity of the marine environment and the high-accuracy and rapidity required by USVs to complete complex marine missions, such as water quality detection, underwater pipe-laying, rescue operations and so on, a novel hierarchical sliding mode base on non-singular terminal sliding mode control (NTSMC) method is designed for underactuated USVs to ensure that all tracking error can faster converge to a neighbourhood around zero within finite time and address effectively the singularity problem which always exist in terminal sliding mode control (TSMC). The underactuated problem is addressed by hierarchical sliding mode technique. Meanwhile, the dynamic surface control (DSC) is employed to address the explosion problem of computational complexity in traditional method. Further, a novel finite-time disturbance observer (FDO) is devised to estimate accurately the unknown environmental disturbances and for practicality, a saturation constraint function is used to limit the input of the controller. Finally, the effectiveness and stability of the proposed method are validated by simulations and comparisons.","PeriodicalId":37058,"journal":{"name":"Cyber-Physical Systems","volume":"397 1","pages":"263 - 285"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77350461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a particular type of behaviour recognition, VioBD aims to identify whether the behaviours that occurred in the scene is aggressive, such as fighting and assault. To comprehensively analyse the current state and predict the future trend of VioBD research, we survey the existing approaches of VioBD in this work. First, we briefly introduce the basic principle and the challenges of VioBD; Then, we category the existing approaches according to their framework, including the traditional framework, end-to-end deep learning framework, and hybrid deep learning framework. Finally, we introduce the public datasets for evaluating the performance of VioBD approaches and compare their performances on these datasets. Besides, we also summarise the open problems in VioBD and predict its future trends.","PeriodicalId":37058,"journal":{"name":"Cyber-Physical Systems","volume":"93 1","pages":"1 - 24"},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81480515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
