First, the theoretical and simulation analyses of the gas in the system were conducted, and the variation curves of the output thrust and speed of the pneumatic actuator with frequency were generated. Accordingly, a prototype was constructed and tested at a resonance frequency of 607.677Hz. The testing results revealed that the optimum loading pressure of the pneumatic actuator was 0.04MPa, and the maximum thrust force was87.14,which is 1.81 times the pressure of OMPa. The maximum output speed was 26.15mm/s, which is 1.29times the pressure of OMPa. After loading the appropriate pressure, the output speed, output thrust and output step of the pneumatic actuator increased, and the drive voltage and frequency exhibited a linearly increasing relationship within a certain range.","PeriodicalId":143024,"journal":{"name":"2022 International Conference on Wireless Communications, Electrical Engineering and Automation (WCEEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124307799","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}

In this paper, a deep sparse representation model is proposed for super-resolution image reconstruction. We firstly study the decomposition of sparse coefficients and the construction of over-complete dictionary, and then use the K- VSD algorithm to extract the image sparse feature. Finally the deep feature migration model is designed to refine image features with deep convolutional neural network (CNN). The experiments carry out on the perspective single-channel, multi-channel and pixel-wise amplitude reconstruction. Both subjective assessments and objective metrics demonstrate that the proposed method has a good reconstruction effect.","PeriodicalId":143024,"journal":{"name":"2022 International Conference on Wireless Communications, Electrical Engineering and Automation (WCEEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122418370","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}

In order to clarify the harmonic responsibility of fresh energy stations, it is necessary to determine the source of harmonics. This paper proposes a harmonic power detection method based on instantaneous reactive power theory on the basis of the harmonic power analysis. This method identifies the source of specific harmonic according to the direction of harmonic power by detecting the power of different order harmonic. The corresponding simulation detection platform is built to verify the effectiveness and correctness of this method. The results show that different harmonics should be judged separately when identifying the harmonic direction of new energy stations, rather than simply using the direction of total harmonic power.","PeriodicalId":143024,"journal":{"name":"2022 International Conference on Wireless Communications, Electrical Engineering and Automation (WCEEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131525959","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 INS has the characteristics of short-term high accuracy and strong anti-interference ability, but the position error will accumulate with the extension of time. In order to further improve the accuracy of the traceless Kalman filter (KF) in Beidou/inertial conduction,.a Back Propagation (BP) neural network aided approach is developed in combination with improved differential evolution algorithm (DE). Specifically, we designed a new BP network that fuse multi features of signals. the INS and Beidou fusion data are collected as samples to train the BP neural network. Then, the improved DE algorithm is employed to optimize KF, attaining superior fusion efficiency. Simulation results demonstrate that the stability and accuracy of position have been significantly improved compared with the original combinatorial positioning model.","PeriodicalId":143024,"journal":{"name":"2022 International Conference on Wireless Communications, Electrical Engineering and Automation (WCEEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127501350","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}

However, due to the complexity of elliptic waveguide, the study of waveguide wall current is always one of the hot spots and difficulties in this field. In this paper, the method of electromagnetic theory derivation and fitting is used. Mathieu function is obtained by separating variables in the elliptic coordinate system, and the field structure in the waveguide is solved by Longitudinal Field Method. Then, the wall current distribution is obtained through the boundary conditions. The results are simulated, analyzed and discussed. The method presented in this paper is helpful for the application of elliptical waveguide, especially for the design of the relevant devices.","PeriodicalId":143024,"journal":{"name":"2022 International Conference on Wireless Communications, Electrical Engineering and Automation (WCEEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114468671","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}
