The kinematic equation of flexible arm space robot which includes elastic variable is established in the form of generalized Jacobian matrix. Continuous trajectory planning algorithm of flexible arm space robot in inertial space reference system is designed based on the kinematic equation. The simulation shows that planned rotary movement law of space robot arm joints may compensate for the impact that vibration of space robot flexible links gives to the end position of space robot arms, and ensure the end of space robot arms along the expected trajectory.","PeriodicalId":376265,"journal":{"name":"2012 Third International Conference on Intelligent Control and Information Processing","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131090058","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 solve this problem, Pedersen et al. proposed recently an effective algorithm called BLUES (BLind Underdetermined Extraction of Sources) by combining ICA and time-frequency masking, and it works well on instantaneous/convolutive mixtures of both speech and music. One key ingredient to BLUES is the stopping criterion of the separation process, where the condition number of the outputs is compared with a fixed threshold in the original version. However, as audio recordings are always varying in speech sources and their number, using a fixed threshold would not fit in with these changes, and then deteriorate the overall performance. As such, we propose a threshold update strategy to improve BLUES by adapting the threshold with an increasing rate to find the most suitable condition number. A new criterion based on detection of the number of the sources is then presented to stop the algorithm. The experiments are carried out by using the synthetic and real recorded underdetermined mixtures. The results show that our approach obtains improved performance compared to the original BLUES when the number of the speeches included in the underdetermined mixtures is increased.","PeriodicalId":376265,"journal":{"name":"2012 Third International Conference on Intelligent Control and Information Processing","volume":"1 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131564029","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}

By using RBF (radial basis function) neural networks to approximate the uncertainties of systems, the problem of singularity is avoided and the trouble caused by \"explosion of complexity\" in traditional backstepping methods is removed by taking advantage of DSC (dynamic surface control) technique. In addition, the input saturation constrains are taken into consideration in the control design. Finally, this scheme guarantees that the closed-loop system is uniformly ultimately bounded and the tracking error converges to a small neighborhood around zero. The simulations on aircraft are given to demonstrate the effectiveness of the proposed scheme.","PeriodicalId":376265,"journal":{"name":"2012 Third International Conference on Intelligent Control and Information Processing","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131565838","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}

Active Disturbance Rejection Control (ADRC) is proved to be very effective control method because it is independent of mathematical model of the plant and can compensate the internal and external disturbances dynamically. This paper investigates the applications of ADRC in ship motion tracking control and presents the design method of ADRC controller appropriate for ship tracking control. Firstly, ship motion mathematical model is introduced briefly and the linear ADRC (LADRC) is analyzed. Then considering the nonlinear ship track design model as a third order plant after utilizing variable substitution, a LADRC controller is designed by using fourth order linear extended state observer (LESO). At last, the simulation is performed. Simulation results show that the controller has a good tracking performance and disturbance rejection ability and is robust to the ship motion nonlinear characteristic and the external disturbances. The tracking process is fast, smooth and minor energy consumption.","PeriodicalId":376265,"journal":{"name":"2012 Third International Conference on Intelligent Control and Information Processing","volume":"97 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133216356","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}
