The speed sensorless techniques for dtc system are very fascinating and challenging subjects recently, they are received wide attention in the literature. some brief description is provided. the proposed approaches are based on speed model of dtc, motor reference adaptive control, the instantaneous reactive power of motor and the extended kalman filter
無速度傳感器調速系統是直接轉矩控制研究領域內一個非常熱門的研究方向，本文介紹了無速度傳感技術的發展歷史及目前的研究狀況，分別利用直接轉矩控制的轉速模型方法，模型參考自適應方法、電機定子反電動勢以及擴展的卡爾曼濾波器等方法設計了無速度傳感器系統，對于其數學模型和系統構成作了比較詳細的推導。According to the raman selection rule and the pl measurement, it is reasonable to evaluate the quality of galnp / algalnp mqw by analyzing the relative intensity ratio of a1p - lo / to. ( 4 ) a new modified random element isodisplacement ( mrei ) model is set up to calculate the dependence between the long - wavelength optical phonon frequencies and the composition of iii - v - type ab1 - xcx mixed crystals. the second neighbor force constants are still assumed to be a linear variation with the composition, but the two first neighbor force constants can be evaluated to be a negative exponent variation with the composition, using the overlapped repulsive potential of the ion crystal combination
通過實驗我們找到了在這些結構參數上生產gainp algainpmqw的較理想的結果； （ 3 ）首次用喇曼（ raman ）散射方法研究了常溫下的gainp algainp多量子阱結構，除了指認出喇曼光譜中各光學聲子模外，還結合樣品光致發光譜的測量結果，分析發現喇曼光譜中alp - lo to的相對強度比可以在一定程度上評定晶體gainp algainpmqw的生長質量； （ 4 ）在修正的隨機元素等位移? mrei模型的基礎上建立了一個新模型，計算了ab _ （ 1 - x ） c _ x型?族半導體混晶的長波長光學聲子模頻率的組分變化關系。The boom of modern naviation technology urgently requires its navigation system to be more accurate and more reliable. it is unpractical to meet both demands by any kind of navigation equipment separately. when the classical centralized kalman filter ( ckf ) is used in this kind of integration, there will be two disadvantages : firstly, there exists real time computation difficulty
如果組合導航系統按照傳統的設計方法設計成維數龐大的集中式卡爾曼濾波器，則計算量將以維數的三次方劇增，給實時計算帶來困難；且容錯能力較差，一旦某一子系統出現故障，所有正常工作的子系統都會受到污染。But when the classical centralized kalman filter ( ckf ) is used in this kind of integration, there will be two disadvantages : firstly, there exists real time computation difficulty ; secondly, the fault tolerance capability is poor. once one of the subsystems breaks down, all the other subsystems are affected
然而，如果按傳統的集中式卡爾曼濾波器設計組合導航系統時會產生兩個缺點：一是實時計算困難，計算量將以維數的三次方劇增；二是容錯能力極差，一旦某一子系統出現故障，所有正常工作的子系統都會受到污染。分享友人
