Rotor position can be identified at standstill and higher speeds by using one of two spatial saliency based high frequency carrier signal injection methods: rotating vector in the stationary frame or pulsating vector in the estimated rotor frame. Carrier currents for both rotating and pulsating voltage carrier injection are derived by using an IPMSM model for high frequency. An appropriate carrier signal extraction and a spatial saliency tracking scheme for both injection methods are developed for robust sensorless control. By interfering with the spatial saliency, saturation-induced saliencies act as disturbances to the rotor position estimation. Modeling, measurement, and analysis of the undesirable saturation-induced saliencies are presented for both carrier signal injection methods.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"129 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130039983","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}

This technique makes it possible to significantly increase the machine inductance in order to achieve the critical condition for providing wide speed ranges of constant-power operation. The conditions for optimal flux weakening can be achieved while simultaneously delivering sinusoidal back-emf waveforms and low cogging torque. A closed-form analytical model is described that can be used to design SPM machines to achieve optimal flux weakening conditions. This technique is applied to design a 6 kW SPM machine that achieves constant-power operation over a wide speed range. Performance characteristics of this machine are compared using both closed-form and finite element analysis.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"9 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130131931","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}

This work presents a closed-loop current regulation concept for converter fed loads using the generalized space vector (GSVPWM) and generalized discontinuous carrier-based pulse-width modulation (GDPWM) schemes which operates effectively in the linear and overmodulation regions. The harmonic currents generated in these operational modes which naturally degrade the classical PI regulators are eliminated from the controller path by an open-loop harmonic current estimation scheme to ensure current regulation in the synchronous reference frame. The realization of the proposed modulation schemes and current regulation concept are validated by steady-state experimental results and dynamic response of a current regulated inverter feeding an impedance load.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130534187","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 traditional sensorless approaches being on the basis of d-q vector control, neither complex computation tasks nor external precise current sensors are necessary. Therefore, it is suitable for low cost implementation of variable speed drives. The theoretical and experimental studies using 2.2 kW-6700 rpm IPMSM show the proposed sensorless drive meets the requirements for the target application. Moreover, the dynamic simulator of the controller built up on MATLAB/SIMULINK also demonstrates the validity of the proposed sensorless control approach.","PeriodicalId":131410,"journal":{"name":"Conference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting.","volume":"20 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120839297","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}
