An integrated strategy composed of active part and passive part to solve this problem is proposed in this paper. In the active part, the priority of control packets in ICS can be improved through differentiated services which decrease probability of control packet dropout. While in the passive part, a data packet dropout compensator is established to reduce the negative influence of packet dropout. The sufficient conditions for stabilizing the new result model are derived in the form of linear matrix inequalities (LMI). At last, the solvability and effectiveness of the results is evaluated using NS2.","PeriodicalId":188024,"journal":{"name":"2008 2nd International Symposium on Systems and Control in Aerospace and Astronautics","volume":"52 Pt 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128909599","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 approach for texture classification using a new cluster-based feature extraction method that divides the matrices of computed two-dimensional wavelet coefficients into clusters. The features that contain the information effective for classifying texture images are computed from the energy content of the clusters, and these feature vectors serve as input patterns to a neural network for texture classification. The results show that the discrimination performance obtained with the proposed cluster-based feature extraction method is superior to the performance obtained using conventional feature extraction methods, and robust to the rotation and scale invariant texture classification.","PeriodicalId":188024,"journal":{"name":"2008 2nd International Symposium on Systems and Control in Aerospace and Astronautics","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117132885","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}

It is so-called perfect-sampling of MCMC method, which can guarantee that samples are drawn exactly from distribution of flight object attitude estimation.

Another important role is to avoid the temperature varying excessively which will result in the high temperature agglomeration or low temperature agglomeration in boiler. Based on the model and characteristic analysis of combustion system, this paper presents an override control solution which can satisfy the various control tasks requirement. In this design, the control strategy is selected automatically according to the furnace temperature value. When the temperature is normal, abnormal or unsafe, the conventional control, limiting control or shut-down devices with warning will be triggered respectively. The dynamic control process is simulated on an object model, and the quiver phenomenon that often occurs in override control is analyzed and improved. The simulation result shows that this design can deal with the control task of both steam pressure and the agglomeration at the same time, and ensure the device safety and system continuous. Whatpsilas more, the design is proved to be effective in the Wangjiazhai power plant, mining bureau of Shuichen, Guizhou province.","PeriodicalId":188024,"journal":{"name":"2008 2nd International Symposium on Systems and Control in Aerospace and Astronautics","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122910598","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}
