The problem is pertinent to the underlying signed directed graph (digraph) where both cooperation and competition exist between the systems. A state feedback low-gain controller parameterized in a small positive scalar is constructed based on suitably chosen scalar coupling gain and feedback gain matrix to realize the control problem. Bipartite synchronization phenomenon with respect to a leader system is achieved with the designed control law over the underlying signed digraph network where the digraph contains a directed spanning tree rooted at the leader. Finally, the theoretical results are validated using a group of coupled Chua’s circuits which establish the effectiveness of the proposed method.","PeriodicalId":142069,"journal":{"name":"2021 IEEE Second International Conference on Control, Measurement and Instrumentation (CMI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131133584","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}

Condition Monitoring of these motors with the help of Motor Current Signature Analysis is a bit challenging to electrical engineers. This is due to the fact that normal Fourier Transform technique is insufficient in processing the current signals from these motors. So this paper aims at detection of rotor faults (crucial part of condition monitoring) in Brushless DC Motors using advanced Fourier Transform techniques. Short Time Fourier Transform is one such basic technique. So BLDC motor is modelled and analysis is completely done in Matlab software using Time-Frequency and Wavelab toolboxes.","PeriodicalId":142069,"journal":{"name":"2021 IEEE Second International Conference on Control, Measurement and Instrumentation (CMI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129957686","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}
