The attitude estimation accuracy can be improved by modifying attitude matrix with measurement data from other star trackers. The attitude determination algorithm with two star trackers was reviewed firstly, then a modified attitude estimation algorithm using three star trackers is proposed to enhance the precision of the attitude estimation. The extended Kalman filter is used to estimate the attitude of the nonlinear satellite system, and a federated configuration is adopted to process the estimated states and covariance matrices for high accuracy attitude estimation. Using the proposed algorithm, the satellite can perform missions continuously. A mathematical simulation is performed to verify the effectiveness of the adoption attitude estimation algorithm, using a designed PD controller and five reaction wheels as the attitude control system; three star trackers mounted with a titled angle as the measuring system and federated extended Kalman filters as the attitude determination system.","PeriodicalId":114901,"journal":{"name":"Proceedings of the 10th World Congress on Intelligent Control and Automation","volume":"34 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125719171","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}

Moreover, activity introduces several outliers into heart rate series. Heart rate variability analysis under exercise conditions can't be conducted identically to the traditional methods. A heart rate distribution analysis method is proposed to fuse the activity information and heart rate signals which will be used to make heart rate analysis under exercise conditions. Firstly we use Gaussian function to fit RR intervals under various intensity activities, and then establish dynamic model for the parameter μ and σ which is changed with activity intensity. With the distribution of heart rate determined, outliers in RR interval can be detected and replaced according to possibility distribution. In the last, the validity of outlier detection algorithm and the influence of outliers to HRV are verified.","PeriodicalId":114901,"journal":{"name":"Proceedings of the 10th World Congress on Intelligent Control and Automation","volume":"233 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132378741","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}

Belt conveyor is a nonlinear, severe disturbance and time-varying system. So far, most of the existing models are based on mechanism laws, which are very useful for belt conveyor design. However, they are too complicated to be applied to control system design. To facilitate a valid control strategy design, this paper tries to avoid the internal complexities and presents a black-box model of the belt conveyor based on LS-SVM. The simulation tests reveal that it is feasible to establish the model using LS-SVM. Compared with the model based on the NARMA model, the simulation results are shown that the model based on LS-SVM algorithm is superior in data fitting.","PeriodicalId":114901,"journal":{"name":"Proceedings of the 10th World Congress on Intelligent Control and Automation","volume":"237 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132564047","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 dual control system takes advantage of both coil cooling and jacket cooling so that both dynamic and static state performances of the control system get more satisfactory.
