Acyclic potential motion
無環量勢流For the bldcm which has a pseudo - sinusoidal back - emf waveform, this dissertation presents a svpwm control method using six discrete position signals for minimizing the torque ripple. the main aspects for the implementation of this method are analyzed, including the initial orientation of the voltage vector, reasonable choice of the impedance angle and the advance commutation angle, and estimation of the successive rotor positions
針對反電動勢類似正弦的準正弦波反電動勢無刷直流電動機,本文提出一種基於六個離散位置信號的自同步svpwm (電壓空間矢量法)控制方法,用以削弱電磁轉矩脈動,分析了實現這種方法的主要控制環節,包括起動時電壓空間矢量的初始定位,阻抗角與電流超前角的合理選擇以及連續轉子位置的估計等。Acyclic potential flow
無環量勢流Adopting rotor field - oriented vector control methods, through which make the stator and the rotor magnetmotive forces can be kept orthogonal all along during operation of the bldcm, combining hysteresis current modulation ' s current control advantage and space voltage vector modulation ' s torque ripple attenuation advantage, then designing a sort of bldcm hysteresis current svpwm control method
摘要研究採用轉子磁場定向的矢量控制方法使無刷直流電動機定、轉子磁勢矢量始終保持正交,結合滯環調制電流控制和空間電壓矢量調制,設計了無刷直流電動機滯環電流svpwm控制方案。According to the demand of national, provincial and municipal enviroment agency, iaccomplished a report on taihu lake water quality in march 1996, which was submitted to the environmental commission of the state coucil as a meeting material. the report reflects the present state and tendency of taihu lake water quality and analyses the reasons of the pollution and gives suggestions for preventing the pollution. it provides the technical support for the government and plays an important role in policy decision. 2
