The proposed method in dealing with time-delay incorporates a mode-dependent Lyapunov functional and a precise upper estimation for a combination of positive-definite matrices with reciprocal coefficients. A novel sufficient condition for the solvability of the desired mode-dependent filter can be constructed by solving a set of standard LMIs, which guarantees stochastic stability and a prescribed l2-l∞ disturbance attenuation level of the resulting filtering error system. An illustrative example is provided to demonstrate the effectiveness of the proposed method.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130743672","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}

For the reasons of surgeons needing to do much work in preoperative process and many surgical instruments occupying much space in operating room, it is impossible to realize position set by repeated trial and error process in operating room. Therefore, the method of off line simulation is a suitable ways to set laparoscopic robot' position in preoperative process. Through the concepts of service sphere and service region, dexterity distribution of laparoscopic robot is illustrated in workspace, then a robot's position planning method using gradient projection for distance search is recommended. By combining with dexterity distribution of laparoscopic robot and gradient projection method for distance search, a preoperative position planning strategy for laparoscopic robot is given. In the end, simulation and experiment are carried out to validate the effectiveness of planning strategy.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127856969","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 introducing new gain scaling factor, one of them makes it possible to arbitrarily reduce the effect of sensor noise composed of zero-mean random signal, whereas the others cannot reduce the effect of sensor noise under the magnitude of noise. In order to utilize the controller using gain scaling factor, the controller has to be directly connected to plant. However, in practical system, many systems are classified into cascade system since there is actuator between plant and controller. In this paper, we propose an output feedback controller applied to the cascade system by retaining the advantage of the previous controller. More specifically, the controller is composed of two part; in first part, the controller transforms the cascade system to a singularly perturbed system, and then the second part makes the effect of sensor noise be arbitrarily small in the singularly perturbed system.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131675929","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}

But by far most of the traditional methods, relying solely on single information, can not eliminate shadow effectively. This paper describes a mixed approach to deal with the shadow of the foreground objects from video surveillance. Firstly, a new description of local texture operator-LMTO (Local Match Texture Operator) is adopted; it can be an excellent capability in describing the local texture information. Secondly, we propose a new determination mechanism which combines the luminance, texture information and color-ratio of the pixels.

The challenge of video-based face recognition comes from several aspects. First, video data involves many frames, which increases data size and processing complexity. Second, key frames extracted from videos are usually of high intra-personal discrepancy due to variations in expressions, poses, and illuminations. In order to address these problems, we propose a novel semantic based subspace model to improve the performance of video based face recognition. The basic idea is to construct an appropriate low-dimensional subspace for each person, upon which a semantic model is built to classify the key frames of the person into specific class. After the semantic classification, the key frames belonging to the same classes, i.e. the same semantics, are used to train the linear classifiers for recognition. Extensive experiments on a large face video database (XM2VTS) clearly show that our approach obtains a significant performance improvement over the traditional approaches.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115765696","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 brings some challenges to the autopilot design and stability analysis. Indirect robust control strategy is applied to handle this problem. Based on the nonlinear dynamics of the interceptor, a nonlinear system for tracking acceleration commands is presented. Treating the error between the actual inputs and the computed inputs as input uncertainty, a robust control problem is formed. It is equivalent to an optimal control problem of the nominal system with a modified cost functional. The state-dependent Riccati equation approach is applied to solve the nonlinear optimal control to obtain a solution to the robust control problem. Numerical results show the effectiveness of the proposed strategy.","PeriodicalId":250844,"journal":{"name":"2013 IEEE International Conference on Information and Automation (ICIA)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124083927","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 method is based on triaxial transmitting coils and triaxial sensing coils, which are based on the electromagnetic field. Transmitting coils fed with different frequency alternating current (AC) signals comprise the magnetic field source, which can be seen as three orthogonal magnetic dipoles. By extracting the amplitude and phase information from the triaxial sensing coils, 3D position and 3D orientation information of the sensing coils in the pre-defined localization coordinate system can be estimated using an appropriate algorithm. In this paper, an analytic method is proposed to realize the calculation, which can estimate the position and orientation of the sensing coils easily and fast.
