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。Vp3 gene of hl isolate of goose parvovirus derived from recombinant piasmid pproex htb - vp3 was subcloned into ecorl site of psy538, and the reporter gene lacz with promoter pll was cloned into smai site of recombinant piasmid. both vp3 gene and lacz gene were cloned into noti site of psy681, recombinan fpv transfer vector containing vp3 gene of gpv was obtained. the result is basis of construction of recombinant fpv expressing vp3 gene of gpv and gpv genetic engineering vaccine
本研究另從含有gpvh1分離株主要結構蛋白vp3基因的重組質粒pproexhtb - vp3中切取gpvh1株vp3基因片段，將其亞克隆于psy538的ecori位點，然後將帶有痘苗病毒啟動子p11的lacz報告基因平端克隆于上述重組子的smai位點，再用noti切下同時含有vp3基因和lacz報告基因的片段，再亞克隆于psy681的noti位點，構建出含有vp3基因的重組禽痘病毒轉移載體，為構建表達vp3基因的重組禽痘病毒從而制備gpv基因工程疫苗奠定了基礎。Both the mature genes of gloshedobin and gussurobin were cloned into the vector pet - 32a ( + ), strain bl21 ( de3 ), to study their expression in prokaryotic cell. the gene was expressed under t7 promoter with a fusion protein partner of thx. tag and a 6x his. tag at its n - terminal. having been induced by iptg for 4 hours, the recombinant enzyme was examined in the cytoplasm by sds - page analysis
將大連蛇島蝮蛇和長白山白眉蝮蛇毒類凝血酶基因分別克隆到大腸桿菌表達載體pet - 32 （ a ） +中，在t7啟動子下表達出融合蛋白，融合部分為硫氧還蛋白，位於類凝血酶基因上游，並在其n端帶6xhistag標簽以利於表達產物的分離純化，經熱激轉化至宿主菌bl21 （ de3 ）中， iptg誘導斗小時后收獲菌體。This system makes a breakthrough of traditional incremental motion control theories. it breaks the strict ambit between continuum and discrete, speed and position, rotation and step, the space vectors of stator magnetic field and rotor magnetic field are selected as the main control objects, incremental motion control and motion control are combined organically to make incremental motion control develop to large capability, high efficiency, high precision
這其中的交流步進控制理論打破了傳統的增量運動控制思想，打破了連續與離散，速度與位置，旋轉和步進的嚴格界限，以定、轉子磁場空間矢量為主要控制目標，將增量控制與運動控制有機的結合起來，使增量控制向大容量、高效率、高精度方向發展。分享友人
