A lot of insulators of GIS are surrounded by iron hoops in recent years, which can prevent electromagnetic wave from spreading out extremely. So it's difficult to detect the electromagnetic wave from the surface of the insulator. It is a new method to detect the electromagnetic wave diffusing from the pouring aperture in the iron hoop. However, propagation feature of UHF electromagnetic wave diffusing from pouring aperture is undiscovered due to the tiny dimension and special configuration. It's essential to develop an UHF transducer exclusively used in detecting UHF electromagnetic wave diffusing from pouring aperture. Propagation feature was simulated by FDTD (finite-difference-time-domain) method. The UHF transducer of dipole antenna was developed based on the software of CST (Computer Simulation Technology). Ultimately, detection sensibility and validity of the transducer was tested via an experimental platform of 110kV GIS. It is concluded that the electric field principal component of UHF electromagnetic wave diffusing from the pouring aperture is parallel to the short edge of pouring aperture. The primary frequency range is concentrated in 0.8-2GHz. The average equivalent height of the dipole antenna transducer achieves 8.1mm in the range of 0.8-2GHz. Partial discharge detecting sensitivity of the dipole antenna transducer detecting the partial discharge UHF signal can be lower than 25pC.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121324203","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 facilitate the controller design, the problem of autonomous landing is converted from general trajectory tracking problem of a quadrotor to a stabilization problem of relative motion. A four-degrees-of-freedom (4-DOF) nonlinear relative motion model with four control inputs is estimated. An adaptive radial basis function neural network (RBFNN) is developed to estimate the unknown disturbance and is applied to design the controller through a backstepping technique. It is proved that all the states in the closed-loop system are uniformly ultimately bounded and the error converges to a small neighborhood of origin. Numerical simulation results illustrate the good performance of the proposed controller.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127450033","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}

Firstly, the 2-tuple linguistic is used to cope with assessment information of attribute values and weights that represented with linguistic variable. Subjective weights of attribute are calculated by using the weighted averaging operator for 2-tuple linguistic and the objective weights of attribute are determined based on the statistical variance. And subjective weight and objective weight are integrated into combination weight. Then, through the 2-tuple linguistic VIKOR method, the compromise ranking result of alternatives can be determined. Finally, an example analysis is given to illustrate the validity and applicability of the proposed method.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127512931","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, we propose a novel susceptible- negative/positive-recovered-susceptible (SN/PRS) model to depict human behavior disseminating in social networks from microscopical view. Different from previous literature, the discrete SN/PRS model considers the neutralization reaction of multiple behavior, and the marginal diminishing effect. Then the influences of topology structure, degree and ratio of initial fixed infected nodes on system stability are investigated. Results display that the density of two kinds of spreaders have similar periodic oscillations, but various phase diagrams during the behavior disseminating process in different networks. Finally, the countermeasures to prevent the outbreak of negative behavior are proposed respectively.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127526059","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, under the PMSM servo control system which is based on SVPWM control strategy, the traditional PI controller has the disadvantages of weak robustness and poor anti-interference ability. Therefore, the Fuzzy Logic Control (FLC) is proposed to improve the control effect and enhance the robustness of the system. Finally, a simulation model based on the complete system combining the FLC and the MRAS observer is established in the Matlab/Simulink environment to testify the proposed strategy. Simulation results show that the proposed strategy can not only improve the dynamic performance and anti-interference ability of the PMSM control system greatly, but also estimate the rotor speed and angle effectively when the position sensor fails, thus the fault-tolerant capability of the whole propulsion system can be enhanced.","PeriodicalId":409960,"journal":{"name":"2018 Chinese Control And Decision Conference (CCDC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124798409","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 characteristics of high-speed trains, including traction characteristic and regenerative braking, and the railway geographical conditions are fully considered in the dynamic model. Based on discretization analysis of the route, a novel optimal operating strategy consisting of a global optimization process and a further optimization process is developed to reduce the energy consumption. In the global optimization process, genetic algorithm is applied to search the optimal speed at each end of subsection in fixed time. Then, the optimization strategy is further studied to search the speed serial to improve the train operation process. To verify the effectiveness of the proposed operating strategy, the optimization strategy is simulated, and the operation performance of CRH-3 is tested. In comparison to regular train operation strategies, the proposed operation strategy is proved to obtain the favorable results for high-speed trains.
