  1. 1 m 0. 5, the phase - shifted angle 6 is controlled in term of sine law which makes the magnitude of resonant voltage track a reference sine voltage, and the resonant voltage is rectified, filtered, inverted and then the better sine - voltage output is obtained, theoretical analysis and experimental results show that for the resistive load and inductive load, the switches of leading leg of the phase - shift - controlled circuit are always turned on at zvs, and ones of lagging leg are turned on at zvs ( < 0 ) or turned off at zcs ( ( > 0 ), moreover, all switches in the low - frequency inverter are always turned on and off at zvs, the measured circuit efficiency for rated load reaches up to 88 %

    從功率單向流動角度出發,提出了一種lcc諧振型恆頻移相單相高頻鏈逆變電路拓撲,在調制系數0 . 1 m 0 . 5情況下,控制移相角按正弦規律變化,使諧振電壓脈沖列的幅值追蹤參考正弦電壓信號,經過整流、濾、低頻逆變,從而獲得正弦度較好的輸出電壓。理論分析和實驗結果證明對于性負載或感性負載,移相全橋具有超前橋臂電壓開通,滯后橋臂或者電壓開通( _ 0 )或者電流關斷( _ 0 )的軟開關特性,而低頻逆變器的各個開關均實現電壓條件下的開通與關斷。
  2. The matlab program is used to reconstruct the image of objects and by several ways of digital image - processing such as band - pass filtering and v - filtering, the quality of reconstruction image is greatly improved

    利用帶和v型濾等數字圖像處理方法削弱了級衍射斑的影響,提高了再現像質量。
  3. Firstly, we analyze the transient and steady character of single phase high - impedance grounding fault. secondly, based on wavelet analysis on checking mutational signal and direction high frequency protection theory, utilizing zero sequence current and module current, this paper provides a new scheme including fault starting element, fault phase selection element, directional element and main criterion. this scheme can bear high impedance and is immune to system surge and frequency warp, which gets over the shortcoming of the lack of sensitivity

    由於現有的保護方案無法快速有效地切除此類故障,本文在詳細分析了單相高接地故障的穩態和暫態特性的基礎上,從小分析原理出發,利用小變換檢測突變信號的原理,以序電流、模電流等為研究對象,結合方向高頻保護的原理,設計了一套包含啟動元件、選相元件、方向元件、主保護的保護新方案。
  4. ( 6 ) the analysis on singularity configurations of the manipulator were investigated by the singular value decomposition of jacobian matrix, which was treated with the damped least - square method in the motion. from the results obtained it was indicated that the minimum singular value of manipulator calculated by the damping jacobian matrix were far from zero position. velocity, position and accelerate of all the joints of manipulator moved regularly, consequently the problem that the joint of mani

    ( 6 )通過雅可比矩陣奇異值分解進行番茄收獲機械手奇異性分析,並採用尼最小二乘法對機械手運動中的奇異位形進行處理,使番茄收獲機械手最小奇異值遠離點,各關節運動速度、位置和加速度運動無異常動,解決了機械手在奇異位形處某些關節運動無法控制的問題。
