The neural network is trained on-line with a normalized training algorithm, which eliminates the requirement of a bounded regression signal to the system. To ensure the convergence of the training algorithm, an adaptive dead-zone scheme is employed. Stability of the proposed control scheme is guaranteed based on the conic sector theory. To demonstrate the applicability of the proposed method, real-time tests were carried out on a pilot VAV air-conditioning system and good experimental results were obtained.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127087630","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}

If they are not appropriately predetermined, results of segmentation may become considerably worse. To fulfill unsupervised clustering segmentation of visual color images for a mobile robot, this paper proposes a multiprototypes-take-one-cluster (MPTOC) strategy and splitting-merging competitive learning (SMCL). Based on MPTOC, SMCL can adaptively detect the appropriate cluster number of color images.

In some applications, such as uncalibrated visual servoing, the knowledge is too hard to be gained. This paper proposed an iterative learning control for a class of MIMO systems. The controller consists of a Nussbaum-type gain selector for roughly probing proper control gain matrix and a refined compensator learned through repetitive tracking. It is able to guarantee convergence of the learning control even without any knowledge about the system.

In the case of measuring a polished turbine airfoil, however, specular reflection on the surface causes \"non-measurable\" gaps in each optical scan. Conventional techniques like linear interpolation and spline interpolation become ineffective in reconstructing the surface from such \"corrupted\" measurement data sets. This work develops a hybrid technique that combines piecewise cubic Hermite interpolation with linear compensation. The technique preserves the shape well, and generates smooth curvature in the specular reflection gap. In comparison with spline interpolation, it achieves better and more accurate profile fitting.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117090219","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 system is integrated with augmented reality (AR) and visual reality (VR) visualization. Two tracking systems were used on the arm, camera tracking and encoder tracking to simultaneously track the ultrasound probe and surgical tool. Stereo-camera is used to track an optical marker, which is temporary mounted. The marker is removed once the initial location of the arms is computed and encoder-based tracking takes over. On each passive joint of the arm system, a rotary encoder is installed which tells the angle of each joint. Therefore the positions of both ultrasound probe and surgical tool are known. The surgical tool is fitted onto a motorized 2 degree of freedom (DOF) with motorized cutting sequence, which enables cutting planning, probe positioning and controlled tissue cutting procedure. The prototype of the system proved the concept and future work is expected to improve the accuracy.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115945483","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}

Unlike a multi-axes actuating mechanism where the number of electrical inputs typically equal to its number of controllable degrees of freedom, the VRSM offers a large number of distributed electrical inputs as compared to the number of controllable DOF. Since larger number of small coils is used, it not only effectively increases the surface area for heat dissipation, but also allows a small amount of current to flow through each of the coils. This distributed actuation offers an effective means to overcome heat dissipation problems commonly associated with direct-drive actuators for high torque applications. To exploit the advantages offered by this unique feature that provides a greater flexibility in design and control, a good understanding of the key parameters that could significantly influence the motor performance is essential. For this reason, we present in this paper some results of a detailed parametric study on the effects of pole geometry on the thermal and torque performance of a three degrees-of-freedom (DOF) VRSM.","PeriodicalId":252964,"journal":{"name":"IEEE Conference on Robotics, Automation and Mechatronics, 2004.","volume":"47 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132640355","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}
