  1. Due to the complexity of the structure and control of cycloconverter - type three - phase hf link inverter for soft - switching based on phase - shift - controlled full - bridge mode, a simple and optimized vvvf control strategy is proposed. this control strategy includes : produced pwm by space voltage vector ( svm ) and equivalent carrier frequency fe = 1 / te are introduced into the pdm control of the cycloconverter ; softened equivalent pwm wave is generated at the notches of hf voltage pulses ; the harmonious control between regulating pulse width by phase - shifted angle and regulating voltage of equivalent pwm is to minimize the harmonics content of output voltage of the inverter

    西安理工大學博士學位論文針對這種前級移相全橋軟開關周波變流型三相高頻鏈逆變器結構和控制的復雜性，提出了一種實現簡單而整體優化的vvvf控制策略:將空間電壓矢量產生p姍的方法svm和等效載波頻率fe = 1 / te引入到周波變流器的pdm控制;按高頻電壓脈沖前後沿軟化等效p翎波;用移相調節高頻脈沖寬度和等效p姍調壓協調控制逆變器輸出電壓，在滿足輸出電壓條件下使諧波最小。
  2. An algorithm for detecting moving ir point target in complex background is proposed, which is based on the reverse phase feature of neighborhood ( rpfn ) of target in difference between neighbor frame images that two positions of the target in the difference image are near and the gray values of them are close to in absolute value but with inverse sign. firstly, pairs of points with rpfn are detected in the difference image between neighbor frame images, with which a virtual vector graph is made, and then the moving point target can be detected by the vectors ' sequence cumulated in vector graphs. in addition, a theorem for the convergence of detection of target contrail by this algorithm is given and proved so as to afford a solid guarantee for practical applications of the algorithm proposed in this paper. finally, some simulation results with 1000 frames from 10 typical images in complex background show that moving point targets with snr not lower than 1. 5 can be detected effectively

    基於運動點目標在鄰幀差分圖像中所具有的近鄰反相特徵，即運動點目標的兩個位置相鄰近、灰度值一正一負，提出一種在復雜背景下，基於紅外序列圖像的運動點目標檢測演算法.本演算法利用該特徵在鄰幀差分圖像中檢測反相點對，進而構造反相點對矢量圖，最後依據累積反相點對矢量圖中多矢量首位相接的連續性檢測出運動的點目標.文中給出並證明應用本演算法能以概率1檢測到運動點目標的收斂性定理.對典型復雜背景下10幅1000幀圖像的模擬結果表明，當信噪比大於或等於1 . 5時，可以有效檢測出運動點目標
  3. This paper emphatically researches some typical search algorithms based on block matching of motion estimation, such as 155, fss, tdl, cs and ds. aimed at questions existing in these algorithms, under the elicitation of man vision system, the author designs a new integrative pattem ( sdp ) ftom the bionic view, which shows a parallel processing idea of coarse location and accurate orientation, and then presents a new square - diamond search ( sds ) algorithm for block matching motion estimation. the results of experiment prove that not only the new sos is much faster than above traditional algorithms, but also its psnr and visual quality of the retrieval images are better than those of other algorithms, and as nearly good as that of fs

    本文重點研究了三步法（ tss ） 、四步法（ fss ） 、二維對數法（ tdl ） 、交叉法（ cs ）和菱形法（ ds ）等經典的基於塊匹配的運動估值演算法；針對它們存在的問題，在人眼視覺系統的啟發下，從仿生學的角度設計了一種新的綜合模板（ sdp ） ，它體現了粗定位和準確定位并行處理的思想，在此基礎上提出了一種新的用於塊匹配的搜索演算法?正方形?菱形搜索（ sds ）演算法；實驗證明：該演算法的搜索速度比fs 、 tss 、 fss 、 tdl 、 cs和ds都快，而且根據運動矢量恢復出的圖像在psnr和主觀視覺效果方面都和fs相當，比其它演算法要好。
