However, there are still many limitations in largescale information flow perception modeling and performance optimization. In this paper, the Mixed Logic Dynamic modeling method of IoT information flow perception is studied. The IoT sensor nodes, controlled nodes and coordination nodes are used to describe the system application scenarios, whereas the automaton is used to carry out internal information transmission, This lays an important foundation for the coordination and optimization of the system. Then, an open queuing method based on large-scale information flow perception modeling and network delay analysis method is proposed. By analyzing the end-to-end delay of the node path and the average delay analysis of the whole queuing network, the open queuing is obtained, So as to maximize the performance of the perceived network in the IoT. Aiming at the characteristics of distributed data of information flow perception in the IoT, a priority-based queuing network is proposed to model and analyze the aggregation nodes based on embedded multi-core System on Chip (SoC), which greatly improves the performance of embedded multicore SoC.","PeriodicalId":143976,"journal":{"name":"2021 33rd Chinese Control and Decision Conference (CCDC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115637273","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}

The failure of the aircraft's anti-skid brake will affect the system efficiency and flight safety. Therefore, this paper proposes an aircraft anti-skid brake system fault diagnosis method based on Grey Wolf Optimizer (GWO) and Probabilistic Neural Networks (PNN). First, preprocess the acquired data of five parameters of a certain type of aircraft anti-skid brake system: wheel speed, aircraft speed, braking time, brake pressure, and brake servo valve control current to create a PNN fault diagnosis model. Aiming at the shortcomings of PNN network smoothing factor selection based on experience, the GWO optimization algorithm is proposed to optimize the PNN network to find the optimal smoothing factor. The validity of the optimal GWO-PNN fault diagnosis model created is verified by experiments with the relevant parameter data of the brake system. The results show that the GWO-PNN-based aircraft anti-skid brake system fault diagnosis method proposed in this paper can effectively solve the problem of poor fault diagnosis effect caused by the artificial setting of the smoothing factor of the probabilistic neural network, avoiding the interference and influence of human factors. It has a good fault diagnosis performance. The fault diagnosis accuracy rate of the GWO-PNN model is as high as 95%, which is better than the fault diagnosis of the PNN and Back propagation (BP) diagnostic models.","PeriodicalId":143976,"journal":{"name":"2021 33rd Chinese Control and Decision Conference (CCDC)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115755513","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}

Such configuration eliminated DC/AC conversion and simplified the control objectives design, being DC-grid voltage regulation and curretn sharing. This paper develops a stochastic distributed washout filter-based control scheme that can achieve current sharing of DGs and voltage restoration of DC bus in mean square subject to additive noises and time delays over fading networks. Since the cyber channels are exposed to inherent additive noises and time delays, the information exchange among multiple and cooperative DGs may be disturbed in fading communication networks, where fading may either be due to noises, delays, and shadowing from obstacles affecting the wave propagation. As a results, fading makes every DG receives incomplete/imprecise information from its neighbors. To dispel the adverse influences of noises and time delays over fading networks, a washout filter-based distributed noise-resiliency control algorithm is developed for DC microgrids, in which only the current state variable is exchanged among DGs with the local decentralized voltage controller. By introducing stochastic theory and Lyapunov stability function, the criteria for the stability analysis and delays boundedness considering noise interferences is derived to ensure the stability operation of the whole closed-loop DC network. The obtained results show the effectiveness of the proposed strategy by a tested DC microgrid in OPAL-RT real-time simulator.","PeriodicalId":143976,"journal":{"name":"2021 33rd Chinese Control and Decision Conference (CCDC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121269361","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}
