In particular, demagnetization effects are analyzed using the finite element method. Two different stator winding configurations are considered in the analysis, series and parallel connected windings. From this analysis, a fault detection strategy based on the information contained in winding-current spectrum is proposed. A fault severity factor is also proposed to quantify residual magnetism losses (demagnetization) on a single magnet. This factor is practically independent from the motor load conditions. Experimental results are presented to validate the proposal.","PeriodicalId":256385,"journal":{"name":"2010 IEEE International Conference on Industrial Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128186037","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}

Electrochemical capacitors are electrochemical devices, which have a similar behavior that conventional capacitor, but with much more capacitance.

The power converter chosen for this work is a bidirectional boost converter, with the storage element (Electrochemical capacitor) in the low voltage side. Being the high voltage side, of the boost converter, a constant voltage bus. The power converter exposed is a variable structure system (VSS), which has two operation modes. Switching between these modes is governed by a control laws based in a state plane analysis. It is shown that the strategy control is able to be used for bidirectional operation.

Thus, robots need to be able to detect and track human bodies and faces, and obtain human positions and orientations to achieve effective human-robot interaction. It is difficult, however, to robustly obtain such information from video cameras alone in complex environments. Hence, we propose to use integrated sensors that are composed of a laser range sensor and an omni-directional camera. A Rao-Blackwellized particle filter framework is employed to track the position and orientation of both bodies and heads of people based on the distance data and panorama images captured from the laser range sensor and the omni-directional camera. In addition to the tracking techniques, we present two applications of our integrated sensor system. One is a robotic wheelchair moving with a caregiver; the sensor system detects and tracks the caregiver and the wheelchair moves with the caregiver based on the tracking results. The other is a museum guide robot that explains exhibits to multiple visitors; the position and orientation data of visitors' bodies and faces enable the robot to distribute its gaze to each of multiple visitors to keep their attention while talking.","PeriodicalId":256385,"journal":{"name":"2010 IEEE International Conference on Industrial Technology","volume":"430 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133965388","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}

Despite these advantages, stability for this class of predictive control technique remains as an open problem.

The experimental results showed that the overall robustness of the SBW system was not sacrificed through the usage of analytical redundancy for sensors along with the designed FDIA algorithm.
