  1. This paper is based on " the remodeled item of the 122mm automatic barbette servo system ". it introduced the controlled project of brushless direct current motor realized by dsp at first. on the base of analyzing and studying the driving wave of the brushless direct current motor thoroughly and fully, it carried on the servo system ' s simulink and presented the concrete software and hardware ' s devise of the whole system in the end

    本論文的撰是以「 122mm自行迫榴炮伺服控制系統的改型項目」為基礎,首先介紹了dsp實現無刷機的控制方案,在深入、系統的分析和研究了無刷機驅動波形的基礎上,然後進行了伺服控制系統的模擬,最後給出了伺服控制系統具體的軟硬體設
  2. In this paper, they are set forth at first that the kinds of computer - simulation of electronic devices, the development and the requirements of mosfet ' s model and the way of gain the models " parameters, the dc models have been bui it in chapter 2 and the models of big signals have been deduced in chapter 3, they are different from the equivalent circuit models in the traditional software pspice that they come from the numer i ca i - s i mu i at i on wh i ch is based on the essence equat i on, so the precision of simulation is enhanced ? mosfet ' s small signal models of low frequency, intermediate frequency and high frequency have been built in chapter 4 and chapter 5, although the equivalent circuit models in pspice are used for reference to bui id them, they have their own characteristics which are analyzed at a i i kinds of situations, so that the simulation software for mosfet can be written according them and it i s a i so benef i c i a i for us to catch the gen i us character i st i cs of mosfet and to d esign all kinds of applicable devices the correctness of the models is simply proved in chapter 6

    本文首先介紹了子器件算機模擬的分類、 mosfet的建模發展動態、對器件模型的要求以及模型參數的提取方法。在第二章中建立了mos晶體管在壓條件下的工作模型;第三章推導了mosfet的大信號模型,這兩類模型不同於傳統模擬軟體例如pspice中的等效路模型,而是從模型方程出發,採用數值模擬的方法,提高了模擬的精度。第四章和第五章分別建立了mos晶體管低頻、中頻、高頻的小信號模型,雖然借鑒了pspice模擬軟體中用等效路模型的方法,但是本文分別討論了準靜態和非準靜態時器件的本徵部分以及包含非本徵部分工作于低頻、中頻和高頻條件時的模型,可以根據這些模型編相應的模擬軟體,這樣在做器件的模擬分析與器件設的時候,就可以利用模擬軟體逐步深入地分析器件在不同的條件下和器件的不同部分在工作時的各種小信號特性,有利於抓住器件工作的本質特性,設出符合要求的各類通用和特殊器件。
  3. This thesis chooses b spline wavelet that adapts to the analysis of power system signal, and uses the wavelet transformer to analyze the magnetizing inrush current and inner fault current. a transformer microcomputer protection was designed in this thesis, and in the base of intermission angle principle, a new criterion was established, which pierces through the traditional method with accurate measurement of intermission angle, but analyses the wave by wavelet transform. this criterion is lower in hardware, so it will be realized in the existing hardware

    本文選擇適合力系統信號分析的b樣條函數作為母小波,對勵磁涌和內部故障進行小波分析,並設微機型變壓器保護基本配置,在以往間斷角原理鑒別勵磁涌的基礎上,突破傳統精確測量勵磁涌間斷角的方法,接對信號小波變換后的波形進行分析,建立一個新的鑒別勵磁涌判據,該判據對硬體要求不高,可以在現有一般硬體平臺上實現;並編以b樣條函數為母小波的小波變換判據演算法程序。
  4. Moreover, it introduces the bldcm cad software which is widely used in the motor field and proposes the designing thoughts, and also gives the structure frame about this software. at the end it puts forward how to solve some technological hard problems about this software

    項目中機設採用了作者參與開發的稀土永磁無刷動機cad軟體,在文中也對該軟體進行了介紹,給出了關于該cad軟體的主要設思想和結構框架,並對軟體編中的一些技術難點提出了有效的解決途徑和方法。
