In view of the limitation of the traditional inversion theory and method of the gravity and magnetic field, professional an yulin, etc, worked in china university of geoscience, has come into being the theory system of the all - direction imagery for local gravity and magnetic sources after having researched a few years. the theory system broke through the thinking method of traditional theory system, researched all - direction imagery of the 2d local gravity and magnetic sources by means of complex function theory and researched all - direction imagery of the 3d local gravity and magnetic sources by means of spherical harmonic analysis theory, developed greatly the interpretation theory on the gravity and magnetic field
該理論體系突破了傳統的重、磁場解釋理論體系的思維方式,採用復變函數理論研究二維局部重磁場源全方位成像,採用球諧分析理論研究三維局部重磁場源全方位成像,大大發展了重磁學科解釋理論,可以在起伏地形、有背景疊加和高頻干擾等復雜條件下,直接反演加疊代修改,求解分佈在有限范圍內的二維和三維重磁場源異常場的多種反演問題。Specific issues examined are : compensation for the variation of the stator resistance, the offset error of the dc bus voltage, the voltage error generated by the forward voltage drop the dead time of the switches, improvement of the steady state performance, and the speed sensorless control for the pmsm dtc drive system are of major concern in this thesis
定子電阻變化,直流母線電壓漂移,開關器件反向相電壓降、逆變器死區時間引起的電壓誤差的補償,提高系統穩態運行性能以及永磁同步電機直接轉矩控制的無速度傳感器運行方案等問題都是本文研究的重點。轉矩的快速響應是直接轉矩控制演算法的一個卓越的性能。The core of the gravity and magnetic data interpretation is inversion problem, namely, forecasting the position of the sources when the geological and geophysical information is insufficient
重磁資料解釋的核心問題是反演問題,是在缺乏足夠的已知地質與地球物理信息的條件下對場源進行定位預測。
