Two nonlinear simulation methods are designed by curve fitting method and anfis which seem simply and right in the simulation experiment. based on the model different control strategies also were realized in detail such as chopped current control ( ccc ), angular position control ( apc ), amplitude - change ccc and pi control. a simple torque sharing function ( tsf ) method and a tsf controller were designed which decreases torque ripple effectively
文章中還建立一種基於模糊神經網路的非線性模型,並對比分析了三種方法,模擬中確定了電機的最優開通關斷角,在此基礎上實現了電流斬波控制、角度位置控制、變幅值電流斬波控制以及分段雙閉環pi控制,模擬結果表明,它實現了電機的正常運行,很好的抑止了電機轉矩脈動,同時有效地降低了噪聲。In the proposed technique the bemf waveform of bldcm need to be measured in advance at first, through computer simulation and frame transformation, the optimum q - axis current command is achieved. in order to minimize the torque ripple, the d and 0 - axis current command should be zero. furthermore, through reference frame transformation from dqo - axis to abc - axis, we can get the optimum current command in static abc reference frame
在這種控制方法中首先測量出電機的實際反電動勢波形,然後通過計算機擬合和坐標變換,求得產生恆定電磁轉矩所需的q軸電流,令i _ d ~ * = i _ 0 ~ * = 0 ,通過坐標變換,得到三相靜止坐標系a - b - c下的參考電流i _ a ~ * , i _ b ~ * , i _ c ~ * ,利用電流滯環控制來產生pwm信號,由於這種控制方法中電流不會突變,從而可以較好的抑制轉矩脈動。The mode competition is much improved. it may operated with a large electron beam radius, that means decreasing the space charge effects compared with a smaller radius beam with the same current, hence the rbwo may operated with a low axial guide magnetic field. besides, the rbwo with a sinusoidal corrugated coaxial structure is very easy to manufacture
波紋內導體rbwo具有一些突出優點:同軸結構中內導體的存在使系統的截止頻率顯著升高,使得系統尺寸可比普通波紋波導慢波系統大;具有很大的抑制模式競爭的能力和很高的功率容量;可以採用大半徑電子注,在工作電流不變的情況下空間電荷效應大幅度降低,因而可以工作在低磁場狀態;此種慢波結構內導體上的波紋易於加工。The paper first studies tratisiiiittcd power versus transmission angle characteristic, capability to exchange active power and immunity to resonance of static synchronous series ( ompensator ( sssc ) bascd on its stcaty model, and discusses tho capability to control activo and reactive power
論文首先基於靜止同步串聯補償器( sssc )的穩態數學模型,對sssc的功角特性、交換有功、抑制次同步諧振等方面進行了分析研究,探討了sssc的潮流控制能力。Their majestic repose and massiveness, the somewhat angular and flat elegance of their lines, the restraint shown in the treatment of the difficult material ? their whole demeanor indicates a beauty of style that to us, who now can cut the hardest stone like cheese and bread, lacks necessity
他們的文理中流露出的他們的莊嚴的靜止以及厚重的,稍微帶點稜角和平坦的高雅,還有抑制展現在這些難相處的材料的對待中-他們所有這些行為顯示著一種風格的美,對於我們來說,誰能夠象切乳酪和麵包般切割這些最堅固的巖石,已經不再重要。This paper brings forward that asvg is capable of compensating harmonic, negative sequence and zero sequence currents. so asvg can synchronously compensate the reactive current and harmful currents in three - phase four - wire unbalanced system
本文提出靜止無功發生器還具有抑制諧波和濾除負序、零序電流的能力,從而可以用於對三相四線制不平衡系統同時進行無功補償和有害電流濾除。Block or inhibit the release and absorption of glucose into the blood stream
