噪聲抑止 的英文怎麼說
中文拼音 [zàoshēngyìzhǐ]
噪聲抑止
英文
noise quieting-
Two nonlinear simulation methods are designed by curve fitting method and anfis which seem simply and right in the simulation experiment. based on the model different control strategies also were realized in detail such as chopped current control ( ccc ), angular position control ( apc ), amplitude - change ccc and pi control. a simple torque sharing function ( tsf ) method and a tsf controller were designed which decreases torque ripple effectively
文章中還建立一種基於模糊神經網路的非線性模型,並對比分析了三種方法,模擬中確定了電機的最優開通關斷角,在此基礎上實現了電流斬波控制、角度位置控制、變幅值電流斬波控制以及分段雙閉環pi控制,模擬結果表明,它實現了電機的正常運行,很好的抑止了電機轉矩脈動,同時有效地降低了噪聲。The algorithm can effectively separated the small moving target from the rela - tively stationary backgrond according to the differences among the small moving target, back ground interference and noise by inhibiting the background and enhancing the target
這種演算法根據運動小目標,背景干擾和噪聲在圖象序列中的差異,能夠抑制背景,增強小目標並將其從相對靜止的背景中有效地分離出來。This algorithmmerit is may delete the background picture in with the person faceimage same fixed region, not only can effectively restrain thebackground noise, reduces by mistake examining rate, moreover also canreduce the person face examination scope, speeds up the examinationspeed
該演算法的優點是可將背景圖像中與人臉圖象相同的固定區域刪除,不僅能有效地抑止背景噪聲,減少誤檢率,而且還能縮小人臉檢測范圍,加快檢測速度。
