The paper proposes a synthetic method of fuzzy evidence functions. Then a synthetic rule is also built based on distance testing. Instead of using the fuzzy synthesis method in previous methods, it introduces distance testing between fuzzy sets and the weight of fuzzy focused components to compute the contribution factor of evidence functions, and modify the basic probability assignment values of focused components according to novel fuzzy synthesis rule. Several numerical examples are made to demonstrate the effectiveness. The results show that the proposed approach could catch more data from the transformation of the focused component in process industry.","PeriodicalId":262938,"journal":{"name":"2018 10th International Conference on Modelling, Identification and Control (ICMIC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115146176","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 interconnected system involves two cascade nonlinear subsystems. In solving the invertibility problem, we give a necessary and sufficient condition for an interconnected system to be invertible, which says that the individual subsystems should be invertible. When individual subsystems are invertible, we present an algorithm for finding inputs of local subsystems that generate the given global outputs in a finite interval.

The weight of each group of features in the decision-making process is characterized by the features' importance. This paper introduces evidence synthesis theory to overcome the evidence conflict in decision-making and to improve decision precision. Final land-cover objects labels are predicted through ensemble algorithm based on random forest and weighted D-S evidence synthesis.

When the STATCOM compensates the unbalance loads of the network, the DC voltage will contain the second harmonic. The second harmonic has influence on the current control loop, and the network currents will contain the third harmonic and negative currents. The direct-axis component and the quadrature-axis component currents contain the second harmonic which has influence on dynamic characteristics of the current control loop. In this paper, the mathematical model of the STATCOM is established. And a novel control strategy based on PR control and notch filter is proposed. The notch filter suppresses the second harmonic in the DC voltage, and the negative currents and harmonics the STATCOM generated is filtered. With the PR control method, the second harmonic of the direct-axis component and the quadrature-axis component currents could be tracked precisely in real time. And the direct-axis component and the quadrature-axis component currents are compensated precisely and dynamic characteristics could be guaranteed. With the control strategy, the DC capacitor is used to buffer the unbalance power, and the STATCOM compensates the unbalance currents precisely.

The principle of this controller is twofold: 1) an integrated model of the photoelectric platform dynamics combined with the UAV body motion induced disturbance model is established as the internal model, 2) The deviation of the system output is taken as the expected output of the internal model. Furthermore, the internal model input is solved by a modified unknown input observer (UIO). Finally the control is completed by the feedforward of solved input.

In order to solve these issues, a topology discovery algorithm based on multi-protocol is proposed in this paper. At first, the advantages and disadvantages of the topology discovery method based on a single protocol are analyzed. Next, the existing topology discovery algorithm based on the SNMP protocol and the LLDP protocol are improved. Then, the principle of multi-protocol topology discovery algorithm is elaborated. The algorithm is based on SNMP protocol and supplemented by LLDP and ICMP protocol. Experimental results show that the topology discovery algorithm based on multi-protocol has better network adaptability and detection integrity than the single protocol based topology discovery algorithm. Therefore, the multi-protocol topology discovery algorithm is feasible and advantageous.","PeriodicalId":262938,"journal":{"name":"2018 10th International Conference on Modelling, Identification and Control (ICMIC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126958523","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}
