Then , an open - loop control is designed to suppress decoherence , which is shown to be capable of asymptotically decoupling a part of the dynamic variables of the system from the environmental noises 然后,引入開環(huán)控制抑制退相干,并證明該控制可使系統(tǒng)狀態(tài)中的部分分量與環(huán)境噪聲漸近解耦。
At last , we carry on a series of control experiments on the model of robot , verify the open - loop control method put forward in the former document 最后,在具有非驅(qū)動(dòng)關(guān)節(jié)的機(jī)器人模型上進(jìn)行了一系列控制實(shí)驗(yàn),通過這些實(shí)驗(yàn)來驗(yàn)證了以前文獻(xiàn)中所提出來的控制模型,以及開環(huán)控制方法的正確性。
The absolute and relative stability of multi - machine is analyzed intuitionally using the open - loop frequency characteristic charts and the performance index of open - loop frequency domain for each decoupling single - machine 頻域分析法在多機(jī)系統(tǒng)小擾動(dòng)穩(wěn)定方面的研究尚沒有達(dá)到工程實(shí)用的要求。
In recent years , with the development of the ds - ss and the theory of all digital receiver , the open - loop structure based forward estimation attracts more attentions 正是由于閉環(huán)結(jié)構(gòu)的這些缺點(diǎn),近年來,隨著擴(kuò)頻通信和全數(shù)字接收機(jī)理論的發(fā)展,基于前向估計(jì)同步參數(shù)的開環(huán)結(jié)構(gòu)越來越受到人們的重視。
The open - loop system is normally used in simple point - to - point , or positioning systems , although improvements in technology have made it possible to install the system in contouring systems as well 雖然技術(shù)的進(jìn)步已使等值線系統(tǒng)安裝在系統(tǒng)中成為可能,但開環(huán)系統(tǒng)通常只在簡(jiǎn)單的點(diǎn)對(duì)點(diǎn)或配置系統(tǒng)中應(yīng)用。
Then the thesis detailedly dissertates its research pivot : the software realization of sensorless commutation detection based on the method of back electromotive force ( bemf ) and open - loop commutation start - up 然后,詳細(xì)論述了本文的研究重點(diǎn):基于反電動(dòng)勢(shì)法的五位置傳感器換相檢測(cè)和開環(huán)換相起動(dòng)的軟件實(shí)現(xiàn)。
In section 2 . 6 , we show the open - loop system ( 1 . 1 ) - ( 1 . 3 ) is exactly observable . this provides us with an effective method to study the stability of non - dissipitiwe flexible beam systems with boundary feedback 縱觀第二節(jié)到第五節(jié),它為我們今后研究非耗散邊界反饋彈性梁振動(dòng)系統(tǒng)的穩(wěn)定性提供了一個(gè)非常有效的方法。
Since a magnetic levitation system is usually strongly nonlinear and open - loop unstable , it is an important task to construct a hign performance feedback controller to control the position of the levitated object 由于磁懸浮系統(tǒng)有很強(qiáng)的非線性及開環(huán)不穩(wěn)定性,所以設(shè)計(jì)一高性能的反饋控制器來控制懸浮目標(biāo)是一件非常重要的任務(wù)。
Both an open - loop and a close - loop measuring system are established for detecting vibration of the resonant beams and the response of the resonant frequency at different applied pressure loads , based on special lockin amplification technology 利用鎖相環(huán)微弱信號(hào)檢測(cè)技術(shù)自行研制建立了開環(huán)頻率特性測(cè)試系統(tǒng)及閉環(huán)自激測(cè)試系統(tǒng)。
