However, most attentions are attracted on how to form and retain a rigid formation. In many practical situations, due to the tasks and environment are dynamic and uncertain, rigid formation may not obtain the best performance. In this paper, a flexible formation concept is proposed, which is described in a probabilistic formation form. The effect of the idea is studied in a CMOMMT problem. Simulation's results show that the flexible formation algorithm based on the proposed idea performs better than the rigid formation algorithms.","PeriodicalId":155562,"journal":{"name":"IEEE ICCA 2010","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114345051","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}

A PCH model of induction motor is established. The induction motor and controller are interconnected, and desired closed-loop PCH system structure is obtained by the feedback control. The desired closed-loop Hamiltonian function is given. The controller and load torque observer are designed. The equilibrium stability of the closed-loop system is also verified. Using SVPWM signal transformation method, speed regulation of induction motor is implemented by controlling the duty ratio of every converter switch.

Recognition of TCM pulse has received more and more attention in recent years. Extracting proper features is crucial for satisfactory classification. While most of previous methods for feature extraction of TCM pulse have no specific correlation with the mechanism of TCM pulse, a hemodynamics method is used to calculate the pulse waveform velocity (PWV) and pulse reflection factor(R), which reflects the principle of TCM pulse diagnosis. Then K-Nearest Neighbor (KNN) algorithm is employed to classify the data and double cross-validation method is used for accuracy assessment. An average accuracy rate of more than 97.8 % is achieved. It is concluded that the PWV and R may be used as the features for the classification of TCM pulses.","PeriodicalId":155562,"journal":{"name":"IEEE ICCA 2010","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124486860","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 objective is to design an admissible state estimator guaranteeing the asymptotic stability of the resulting filtering error system with a prescribed ℋ∞ disturbance attenuation level. Based on a piecewise quadratic Lyapunov function combined with S-procedure and some matrix inequality convexifying techniques, two different approaches are developed to the robust filtering design for the underlying piecewise affine systems. It is shown that the filter gains can be obtained by solving a set of linear matrix inequalities (LMIs), which are numerically efficient with commercially available software. Finally, a simulation example is provided to illustrate the effectiveness of the proposed approaches.","PeriodicalId":155562,"journal":{"name":"IEEE ICCA 2010","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124729949","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}
