Thirdly, in order to meet the demand of budget balance, an improved model based on optimal allocation model was presented and several payment rules were proposed to solve this model.

Furthermore, it has non-linear and multi-variable coupling characteristics and so on. Therefore, it's a big challenge with the real-time and reliable attitude control. The three degree-of-freedom helicopter model was used as the controlled object. Through the research of modeling, controller designing and simulating, the application of control theory and technology can be made full use of in the complicated system. PID was introduced as the traditional method. Specific to the defects of PID, the fuzzy control algorithm was used to conquer the defects of pure PID controller. Based on the respective advantage of PID and fuzzy controller, PID and fuzzy controller were combined together as one controller which fit together with switch and weighted value. It optimized the flying gesture of the helicopter.

Recently, a simultaneous matrix diagonalization (SMD)-based method has been proposed without any need of sparsity assumption on sources. Instead of using SMD technique, we propose a fixed point algorithm, which estimates the columns of the mixing matrix sequentially one by one. Computer simulations are presented in order to demonstrate that the proposed algorithm has the ability to identify the mixing matrix, and its performance is comparable to that of SMD-based algorithm.","PeriodicalId":227938,"journal":{"name":"2010 Chinese Control and Decision Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116732028","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}

This paper presents a smooth VSC approach for automatic train speed and position tracking control under varying operation conditions. In contrast to most existing methods that either assume the availability of resistance forces for feedback control design, or consider constant resistance coefficients, we consider the case that the basic resistance forces and additional resistance forces are both time-varying and unknown. A smooth VSC method is proposed to achieve high precision position and velocity tracking. The fundamental idea behind this method is to directly design the control rate, instead of the control action itself, thus the chattering problem in most existing VSC methods is removed because the integration of the control rate smoothens the control action.","PeriodicalId":227938,"journal":{"name":"2010 Chinese Control and Decision Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117073905","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}
