Firstly, the main problems arise from non-orthogonality, different sensitivity and bias of the three axes are analyzed. Then a relevant mathematic calibration model in matrix form is constructed to rectify these errors, and is converted to linear form one. Next, the coefficients of calibration model are identified by SVR algorithm. Practical measurement data of geomagnetic field are used to test, and the results show that the measurement errors of three axes fluxgate sensor in different attitude can be rectified under 50nT from 800nT.Because there is no need of any other auxiliary equipment, the proposed method seems to be a better candidate for fast or field calibration of three axial magnetic fluxgate sensors.","PeriodicalId":227938,"journal":{"name":"2010 Chinese Control and Decision Conference","volume":"53 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":"114539961","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}

Based on the artificial neural network technology and the experimental data specimens, the BP neural network model was established to predict the tribological properties. Three parameters of braking conditions (braking pressure, sliding velocity and surface temperature) were selected as input vectors, and two parameters of tribological performance (friction coefficient and wear rate) were selected as output vectors. By contrast of prediction values and experimental results, it is found that the neural network can predict properly the influencing rules of braking conditions on tribological performance. What is more, the neural network has quite favorable ability for predicting of friction coefficient. While it has bad ability for predicting of wear rate, especially when the pressure, velocity and temperature are high. As a whole, this paper has proved that it is feasible and valuable to use neural network for predicting tribological properties of friction materials.","PeriodicalId":227938,"journal":{"name":"2010 Chinese Control and Decision Conference","volume":"1 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":"116471294","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 study, based on the advantage of RBF neural network control method, a new adaptive sliding mode control method, which is one of the active control algorithms, has been applied for seismically-excited building structures. The undue chattering effect, the major disadvantage of conventional sliding mode controller, has been avoided by introducing the new control method. First, we build the motion equation and design the switching surfaces. Next, based on the RBF neural network control algorithm, we adjust the control gain parameter and then design the neurocontroller. For numerical applications, a three-storey shear building model subjected to ground excitations has been considered. The ground accelerations recorded in two different earthquake events have been used to evaluate the effectiveness of the control algorithm for varied disturbances. The simulation results show preliminarily that our new adaptive sliding mode control method is quite effective: not only can it reduce the peak-response of the ground motion, but also it can keep the chattering effect sufficiently low.","PeriodicalId":227938,"journal":{"name":"2010 Chinese Control and Decision Conference","volume":"5 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":"124137834","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}

However, little attention is paid on its design and only a few papers investigated how to design a fault detection dynamic observer. In this work, we propose an innovative dynamic observer design approach for linear time invariant (LTI) systems subjected to unknown disturbance and possible faults with the aid of the generalized KYP lemma developed recently. The dynamic observer is designed such that the disturbances are attenuated to a specified level to meet the H∞ performance in the concerned finite frequency interval while the sensitivity to the possible faults in its frequency domain is maximized in the H- index sense. The existence conditions of such an observer are given in terms of linear matrix inequalities (LMIs). An iterative algorithm is presented to achieve the solution. The effectiveness of the proposed method is illustrated by a numerical example.","PeriodicalId":227938,"journal":{"name":"2010 Chinese Control and Decision Conference","volume":"11 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":"124153299","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}
