目前紙質的飛機系統圖、原理圖矢量化方法用基本的矢量圖元按其位置來再現原始圖,從而導致矢量后圖中各符號整體信息丟失問題,該文提出的自動符號識別方法可有效地解決該問題,此外改進多級緩沖顯示技術不但可有效地解決cbt中系統圖、飛機原理圖的快速顯示,而且也保證圖形可連續光滑滾動和消除放縮拖動時屏幕閃爍現象。In this thesis the author made a study of asynchronous motor model, designed a hybrid simulation system of dtc and analyzed the characteristics of the dtc system and the existing problems detailedly. due to the large torque ripple of induction motor in dtc system, especially in low speed, this thesis proposed a discrete time space vector modulation and designed a sliding - mode torque and flux controllers based on sliding - mode theory to overcome this drawback
由於直接轉矩控制存在的不足之處主要在於轉矩脈動,特別是在低速運行時這種情況更加突出,針對該問題,本文提出了一種離散時間空間矢量合成法來改善轉矩脈動,並且引入滑模理論,設計了一種滑模轉矩和磁鏈控制器來克服這一缺點。Compensation method of motion among the frames is also an important factor to affect the stability of image sequence, if the image sequence is compensated directly with the acquired movement vectors, it will feel the jumping of frame. in the paper, the parameter to compensate for the current image can be determined by average value filtering and have been applied to given motion model to stabilize the image stream. it can realize smoothly processing the image sequences to assure its stabilization
由於幀間運動的補償方法是影響圖像序列平穩性的一個重要因素,直接用運動矢量進行補償,將會使圖像產生跳躍感,本文提出採用均值濾波的方法來確定各幀的補償量,實現了圖像序列的幀間平滑銜接,提高了動態圖像序列的平穩性。An error detecting method which can prevent the decoding error affecting the next video packet head is used, and a restoration measure for b frame based on the mv prediction which can improve the visual quality has been studied. 3. a novel marking algorithm for ip diffserv based on the transmission condition and the different importance of video streams for decoder has been introduced
2實現了mpeg - 4的差錯檢測、可逆變長解碼rvld和差錯掩蓋方法:對i或p幀紋理區的差錯先用rvld進行解碼,然後對殘留的差錯用空間插值或運動補償方法進行掩蓋,而對p幀的運動矢量mv ,利用圖像的空間平滑特性進行恢復; 3針對b幀差錯的復原,我們還提出了一種基於運動估計的方法。3. based on the comprehensively deep research on the pmsm ' s mathematics model, a newly equivalent sliding mode current controller is presented used by field - oriented control, which improves the stator - current waveform of pmsm, decreases the torque ripple. the conclusion above is verified by the simulation results
