The unknown input and the feedback increase the difficulty of its fault diagnosis. Firstly, this paper proposes a method in theory to detect and recognize the fault in a closed-loop system. This method diagnoses the different faults through an unknown input observer (UIO) as well as a common observer which is set behind the control mechanism. Then a model of the momentum wheel in the satellite is built and the previous theory is applied to the model. In the end, the experimental data demonstrates that this method can successfully detect and recognize the sensor failure, the control mechanism failure and the system parameter failure. The method proposed in this paper has reference value for other non-linear closed-loop systems with unknown input as long as they meet all the conditions.","PeriodicalId":434246,"journal":{"name":"2017 First International Conference on Electronics Instrumentation & Information Systems (EIIS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132940166","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 overcome unreliable wireless channels, we introduce a certain diversity degree by limiting the number of original packets included in one transmission no more than the number of sources. We applied two diversity schemes, which called spatial diversity combined random linear network coding (SDRLNC) and simple spatial diversity (SSD), respectively. We derived bounds of throughput for these two schemes, respectively. Through simulation we got the conclusion that, given a series of parameters, the SDRLNC scheme always has a better performance and there always exists an optimal diversity degree for both schemes for the purpose of obtaining the optimal throughput.","PeriodicalId":434246,"journal":{"name":"2017 First International Conference on Electronics Instrumentation & Information Systems (EIIS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133392576","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}

Phase space reconstruction based on the chaos is the necessary steps to analyze the nonlinear characteristics of complex systems. The C-C algorithm that using the correlation integral is an effective way to estimate the parameters of delay time τ and delay time window Tw of phase space reconstruction. Due to the length limited and noise of traffic flow time series, the τ and Tw estimated by C-C method is with volatility. To reduce value deviation, the C — C average algorithm is used in this paper to reconstruct the phase space, and to get the optimal delay time of short-term traffic flow parameters. Then the maximal Lyapunov exponent is calculated by the small-data method, to determine whether the traffic flow time series is chaotic system or not.","PeriodicalId":434246,"journal":{"name":"2017 First International Conference on Electronics Instrumentation & Information Systems (EIIS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132632540","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}
