結合路橋工程的特點，對靜態gps在路橋工程式控制制測量中的數據處理作了系統的分析和研究： ?對單點定位結果作為起算點的可行性進行了研究，並探討其對基線解算的影響； ?鑒于商家提供的隨機軟體往往不支持利用gps觀測得到工程獨立坐標系中坐標，為工程獨立坐標系gps數據處理提供了一種簡便有效的方法，並編制了相關的處理程序，通過實例驗證，程序是正確的、方法是可行的； ? gps測量得到的是wgs - 84坐標，而實用上需要的是地方坐標系坐標，因而得把wgs - 84坐標轉換地方坐標系坐標。On such a basisthe commonly used monomial error accumulating totals correction method is introduced. the author proposes a coordinate transformation method to deal with its drawbacks of maths model imperfection, not applicable to lange - angle deviation and adding to the difficulties of equipment. while orientating the order of matrices according to the principle of the accordance between coordinate ' s rotating order and the physical process of device measuring, a strict maths model of the influence of axis system deviation on surveying angles is concluded and the corresponding correction method is induced. its far - reaching meanings are as follow : ( 1 ) the maths model of the influence of axis system deviation on surveying angles established by the new method is concluded after considerations for the three deviations simultaneously. changes under all circumstances are included, so it is theoretically a perfection of maths method
在此基礎上介紹了國內目前採用的軸系偏差對測量角影響的經典改正方法?單項差累計改正法，並針對該方法存在的數學模型不完善、對大角度偏差不適用、增加設備調整難度等缺陷，提出採用坐標變換方法，並根據坐標的旋轉次序與設備測量的物理過程相符合的原理定位各矩陣的先後順序，推導出了軸系偏差對測量角影響的嚴格數學模型，歸納建立了相應測量角的改正方法。So the vsr can operate in any power factor. internal model control ( imc ) design concept has been introduced to the unbalanced control system of vsr. with imc design concept, the unbalanced control system not only achieve zero steady state error of sinusoidal ac current, but also obtains strong robustness of the control system
由於在abc和靜止坐標系中，採用比例和比例積分調節器無法實現對時變正弦波信號的無差跟蹤控制，而在dq坐標系中需要用正、反兩套旋轉坐標系構成四個電流內環才能實現對正、負序dq電流的無差跟蹤。Secondly, two carbon fiber reinforced composite beams were fabricated, and their modal frequencies were measured by an experiment method. thirdly, delaminations were modeled by pairs of nodes with the same coordinates but different node numbers, while the modal frequencies of these beams with different delamination location and size were computed by an eas piezoelectric solid element. moreover, a novel method combining computational mechanics and neural network was demonstrated for composite health monitoring ; the first five flexure modal frequencies obtained by fem were modified by a primary revising approach and were used to train the neural network
本文較全面地評述了神經網路的應用模型、改進演算法等，編制了bp神經網路程序：制備了纖維增強復合材料試件，並進行實驗模態分析；利用坐標相同、節點號不同的方法模擬脫層損傷，基於eas列式的壓電固體單元計算了不同脫層損傷情況下的頻率信息；針對基於實驗數據訓練神經網路存在樣本不足的缺陷，本文提出了利用有限元方法對含有脫層損傷的復合材料試件進行數值模擬，以前五階彎曲模態頻率構建訓練樣本的新思路，並提出了一種初步的計算值修正方法，以此構建神經網路的訓練樣本：將實驗模態分析的結果送入訓練好的神經網路進行預測，實現了對復合材料梁的脫層損傷的定位和損傷程度的評估。The main module of sensorless pmsm vector control such as voltage sensing, current sensing, smo rotor position estimation, speed calculation, generation of sine and cosine, vector coordinate transformation, pi regulators, svpwm vector modulation are all accomplished in the pwm interrupt service routines
永磁同步電機無位置傳感器矢量控制的主要模塊如電壓采樣、電流采樣、滑模轉子位置估算、速度計算、正餘弦值生成、矢量坐標變換、比例積分調節器、空間電壓矢量脈寬調制等都是在pwm中斷服務子程序中完成。It is very valuable in the domestic small tft - lcd module testing datum. in touching panel coordinates conversion debugging, collected data are processed and the theoretical formula is amended with good effect of display
