This paper presents a pseudo sensorless deadbeat predictive current control (PSDBPCC) method to improve the estimation accuracy of the rotor speed and position with Hall-effect sensors. In this method the output signals of the Hall-effect sensors are transformed to the Hall vector which contains high order harmonics by Clark transformation. The adaptive vectorial filter (AVF) is introduced to extract the fundamental waves of the Hall vector. The rotor speed and position are estimated from the fundamental waves with an improved phase locked loop (PLL) structure. Compared with the conventional method, the proposed method has higher estimation accuracy in steady state and better dynamic tracking performance. The experimental results verify the effectiveness of the proposed method.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130840393","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}

To suppress the current harmonics, a compound control scheme is proposed for an innovative hybrid converter in this paper. The mathematical model of the hybrid converter is analyzed and divided into two parts: main voltage source converter (MVSC) and filtering voltage source converter (FVSC). According to the characteristics of MVSC and FVSC in output power and switching frequency, two different regular sampling strategies are described and applied. On this basis, the exact MVSC model in discrete time-domain is established, and the current controller with complex vector decoupling is designed. Similarly, a current controller with feedback decoupling is designed for FVSC in the continuous time-domain. Both the current controllers have excellent robustness and dynamic response ability. Finally, the proposed control strategy in this paper is verified by simulation results.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129360477","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 rotor of the resolver represents a simple piece of laminated steel with variable reluctance as in commercial resolvers. The stator part, however, is different. Each stator tooth is replaced with an H-core segment, which contains two windings: excitation and sensing. The design is unified in such a way that the same cores can be used in manufacturing resolvers of different sizes with different pole numbers. The size of the stator is significantly reduced because it can cover only about one saliency pitch of resolver. The solution is especially advantageous in electrical drives where the motor has a large number of poles. However, the side effect, which has a negative impact on the accuracy of a resolver with the proposed stator, should be considered during the design. The side effect is analyzed in the proposed resolver structure using the finite element method (FEM) and some approaches to reduce its negative effect are proposed.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"295 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124276908","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}

In this study, a design space method (DSM) is developed to streamline conceptual designing of a high-speed and high-power electric machine. The method uses analytical equations and a rotordynamic model to determine geometrical dimensions based on the application requirements. These dimensions create a feasible baseline design for the particular application. However, considering the dimensions as design variables and using the baseline design as a starting point, a multidimensional combination and interaction of the design variables and the correlated output for the particular topology of motor and performance range can be further studied for design exploration and optimization purposes. The study includes a test case where the baseline dimensions are determined and compared to an existing machine from literature, and then further explored to identify the sensitivity of different outputs with respect to different design variables. The method enables rapid design iterations, rotordynamics and rotor mass optimization.
