The recognition performance of the traditional feature extraction is lowered due of the difficulty in tracking the dynamic changes of EEG. In this paper the Common Spatial Subspace Decomposition (CSSD) algorithm was improved (named Improved-CSSD), putting forward a kind feature extraction method which has the performance of adaptive ability. This method introduced control parameters, which added the training samples of the assistants to that of the target subject in some way. Finally, based on the data of the international BCI competition database, some simulation experiments were conducted by recognizing EEG signals by Improved-CSSD and SVM. Compared with the traditional CSSD, classification accuracy was increased about 8.26% by Improved-CSSD. The result showed that the approach, proposed in this paper, had a good adaptability and a low time loss.","PeriodicalId":114901,"journal":{"name":"Proceedings of the 10th World Congress on Intelligent Control and Automation","volume":"1 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":"131243270","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 main purpose is to obtain a stable and proper linear filter such that the filtering error system remains robustly stable with a prescribed H∞ attenuation level. Based on the bounded real lemma, a more efficient evaluation of robust H∞ performance can be obtained by a matrix inequality condition which contains additional free parameters. When applying this new matrix inequality condition to be the robust filter design, these parameters provide extra degrees of freedom in optimizing the guaranteed H∞ performance and lead to a less-conservative design. A numerical example is included to illustrate the effectiveness of the proposed approach.","PeriodicalId":114901,"journal":{"name":"Proceedings of the 10th World Congress on Intelligent Control and Automation","volume":"39 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":"130722381","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}

It is shown in [1] that given any initial state of a network of order n >; 3, we can always reach at a consistent status, i.e., either all the nodes are ON or all are OFF. In this paper we consider a more general problem: Given a subset S ⊂ V , can we reach to a state such that the state of each node within S is 1(or 0) while the states of nodes outside S is another?

First, the tracking control problem is converted into designing a regulator for the tracking error dynamics under the framework of finite-horizon optimal control theory. Then, with convergence analysis in terms of cost function and control law, the iterative adaptive dynamic programming algorithm is introduced to obtain the finite-horizon optimal controller to make the cost function close to its optimal value within an ε-error bound. Furthermore, in order to implement the algorithm via dual heuristic dynamic programming technique, three neural networks are employed to approximate the error dynamics, the cost function, and the control law, respectively. In addition, a numerical example is given to demonstrate the validity of the present approach.","PeriodicalId":114901,"journal":{"name":"Proceedings of the 10th World Congress on Intelligent Control and Automation","volume":"69 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":"133567136","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 amplitude-frequency characteristic equation and bifurcation response equation are obtained by solving the dynamical equation using the multi-scale method. The example analysis was carried out on the 1780 rolling mill of Chengde Steel Group. It is shown that the increase of motor's disturbance torque will aggravate the vibration of rolling mill's drive system; the motor's disturbance will enlarge when the angle is too large or too small. Then the reasonable control range of spindle angle is determined. It is best to keep spindle angle between degree of 2 and 5.","PeriodicalId":114901,"journal":{"name":"Proceedings of the 10th World Congress on Intelligent Control and Automation","volume":"6 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":"133583241","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}

We provide distributed kinematic control laws for two different synchronization problems. In the two problems the objective is the same, i.e., to synchronize the orientations of the agents, but what is assumed to be measurable by the agents differs. In problem 1 the agents measure their own orientations in a global reference frame, and obtain the orientations of their neighbors by means of communication. In problem 2 the agents only measure the relative orientations to their neighbors. By using the axis-angle representation of the orientation, we show that simple linear control laws solve both synchronization problems. Moreover we show that our proposed control laws work for directed and connected topologies on almost all SO(3) for problem 1 and on convex balls in SO(3) for problem 2.","PeriodicalId":114901,"journal":{"name":"Proceedings of the 10th World Congress on Intelligent Control and Automation","volume":"62 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":"133704983","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}

Driving situations are divided into cruise control, speed following, inter-vehicle distance adjustment modes. Three corresponding control strategies are proposed depending on the driving modes. Then an algorithm of the longitudinal controller is designed. Not only is the following control of the target vehicle in the same lane achieved, but also, when the target vehicle changed, the following control of the new target vehicle is achieved through the control strategies of inter-vehicle distance adjustment.

Currently there are a lot of ear recognition methods based on 2D images, while 3D data can provide more information. 3D reconstruction methods based on multiple 2D images have a common difficult which is to extract corresponding feature points of different images. In this paper, SFS(Shape From Shading) was used for 3D modeling by only one grayscale image. Light direction was estimated by analyzing singular points, which refers to the greatest grayscale point, in 2D grayscale image. In addition, in order to achieve more accurate 3D modes, the abnormal high brightness of the cavity of auricular concha is processed. The matching accuracy of the model can reach to 84%.
