This robot attains selftransforming capability due to multiple degrees of freedom in its structure and the on-board range-sensing ability. The proposed gait generation and navigation algorithms enable Chaser to reconfigure itself to a shape that is best suited to pass through, over or under the obstacles presented to it. Moreover, the robot has the capability to traverse through various type of terrains by moving on wheels, walking like a quadruple and swimming like humans respectively. These multiple kinds of gaits have been coupled with a terrain navigation algorithm so that robot could identify different kinds of terrains and obstacles and transform itself to navigate seamlessly through them. The performance of Chaser is experientially tested with various real-world obstacles. Experimental results validate its performance.","PeriodicalId":424263,"journal":{"name":"2015 Symposium on Recent Advances in Electrical Engineering (RAEE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126761395","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}

Generator Model is a very extensive and complex model and model-based fault detection techniques are difficult to implement. For this data-driven techniques can be applied which need only the process data to establish FDD systems. This paper presents application of subspace aided system identification method and robust residual evaluation using the process data directly, to detect actuator faults occuring in synchronous generators.","PeriodicalId":424263,"journal":{"name":"2015 Symposium on Recent Advances in Electrical Engineering (RAEE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122725970","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 EEG features are modeled as adaptive autoregressive model and estimated using recurring least square algorithm. Nonlinear classification is performed using multilayer perceptron (MLP) and radial basal function neural network to classify extracted features for a two classes experiment. For validation, hands movement imaginations based experiments are conducted using low price EEG EPOC headset. A comparative study, carried out amongst the nonlinear classifiers and with a linear discriminant analysis, demonstrates the dominance of the MLP as nonlinear classifier.","PeriodicalId":424263,"journal":{"name":"2015 Symposium on Recent Advances in Electrical Engineering (RAEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130927718","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}
