Based on the SRM mathematical model, the strategy analyzes the relations between the torque deviation and the output voltage, and calculates the optimal resultant voltage which could compensate the torque error exactly in one sampling cycle. In addition, the strategy is modified in the commutation overlap to prevent the commutation torque ripple. Compared with the traditional SRM control system, the strategy makes the electromagnetic torque follow the reference torque exactly at every moment and realizes significant improvement in performance. The simulation results verify that the proposed control scheme can reduce torque ripple effectively, preserve the quick dynamic torque response and show good robustness.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"2011 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129136495","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 method, the performance map was obtained by calculating the performance goal over the specified torque-speed range, the integration of the performance goal over the map was used to evaluate the motor. Rather than optimizing motor performance for a given operating point, the method considered all the specific load conditions of the motor, which satisfied the design requirement of high performance motor over wide speed range. A motor efficiency optimization case was presented. The comparative study with the traditional single operation point based optimization was also given. The results demonstrate the effectiveness of the proposed method.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130559114","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}

Three one-phase power factor correction (PFC) circuits for each phase of PMSG, called three-phase PFC rectifier, are employed in this topology. Every stator current is controlled in phase with the corresponding electromotive force (EMF) of the PMSG. Based on the models of the PMSG and the PFC circuits, the EMF is reconstructed and the rotor flux linkage is observed. The phase angle for the current control is derived from the flux linkage using a phase locked loop (PLL). Results of both simulations and experiments verify that sinusoidal AC currents are in phase with the fundamental voltages of the EMFs of PMSG with the proposed sensorless control strategy.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132488666","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}

With the development of large-scale wind turbines and the introduction of flexible structures, vibration problems appear more and more serious. Random wind fluctuation, wind shear and tower shadow effect can all cause large ripples on drive-train torque. In this paper, two controllers are proposed for speed vibration suppression and torque ripple suppression. One is the observer-based state feedback generator torque controller, which can add damping to the first drive-train torsion mode. The other is the rotor collective pitch controller based on Active Disturbance Rejection Control (ADRC), which is designed to regulate generator speed. Both of the controllers are built on the basis of the model linearization method. The simulation results show that the control strategy can significantly reduce drive-train torque ripples, which demonstrates the excellent dynamic performance and robustness of the system, hence proves that the new method will have an important value in engineering application.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132873666","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 small-signal model of the DC/DC converter with the proposed scheme is built, the theoretical analysis results based on which show the relationship between several important variables and the DC-link voltage stability. A PMSM drive system with boost/buck DC-DC converter modeled using MATLAB/simulink, and the typical operation condition in EV is simulated to verify the present strategy.

The key is to use the vernier structure for obtaining the high-speed to low-speed gear effect and achieving the high output torque at low speed operation. Also, the proposed motor drive adopts the DC field winding for performing the flux weakening control at high speed operation. Thus, this new in-wheel motor drive can smoothly operate within the speed range of 0∼1000rpm at different operation modes for EVs. The motor drive and its three-operation modes for EV operation, as well as the steady-state and transient performances are analyzed by using the time-stepping finite-element-method.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130477798","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}
