Sensorless means, that no external position sensors are used and the position is obtained from electrical quantities of the actuator itself. In this work a Reluctance Synchronous Machine (RSM) provides the torque of the drive. For the control an angular position sensor is avoided by using sensorless methods instead. Additionally the radial active magnetic bearings (AMBs) of the drive providing magnetic levitation are controlled without any position sensor. Here, the radial rotor displacement is evaluated by sensorless methods too. Thus, the complete prototype drive works fully without angular and radial position sensors. Finally, the drive system architecture gets reduced to an absolute minimum of components, because both components, the RSM and the AMBs, cover already two main functions. Each combines the functionality of an actuator as well as a sensor within one module. Further, the AMBs and the RSM have a three phase structure and allow the usage of the same three phase voltage source inverters. By this overall system simplification a significant hardware cost reduction is gained which offers new possible applications for high speed drives. In this work the basic principles of the sensorless control methods applied to the RSM and the AMBs are explained, the prototype setup is described and measurement results are presented.","PeriodicalId":234682,"journal":{"name":"2015 IEEE Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134068107","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}

Different approaches for HF injection based temperature estimation are discussed and analysed. The conclusion for HF techniques leads to the design of a recursive least squares base estimation approach which with good properties regarding noise and bandwidth. A model based fusion of three temperature sensors serves as a reference for all experimental estimation results.","PeriodicalId":234682,"journal":{"name":"2015 IEEE Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121491036","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 stator flux observer comprises the voltage model augmented by the current model. The position information required by the current model is derived from the examination of the stator current response due to machine saliency. Unlike the signal injection method, the proposed method utilizes only the applied voltage vectors to the machine stator windings. The simulation results presented verify the effectiveness of the proposed approach.","PeriodicalId":234682,"journal":{"name":"2015 IEEE Symposium on Sensorless Control for Electrical Drives (SLED)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124564415","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}
