例句與用法

1. In general these two pins should be joined together and to the analog ground of the system
   通常，這兩個(gè)引腳應(yīng)該就近連接后再接模擬地。
2. The labels " analog ground " and " digital ground " on these pins refer to the parts of the converter to which the pins are connected , and not to the system grounds to which they must go
   引腳標(biāo)記說明該引腳已連接到芯片內(nèi)部的哪個(gè)部分，并非要把該引腳連接到電路的哪個(gè)參考點(diǎn)。
3. To accept the current signal from high negative voltage circuit , the analog ground is raised to a certain positive voltage , which makes it possible for the signal amplitude to be compressed at the same time of its polarity reversion . a pi control program special for laser gyro current control is brought forward according to the conventional pid control method , in which the control signal is figured out corresponding to the difference between the sample and the reference value by turn of proportion - short step integral - long step integral . and at the end of this paper , a comparison of system performance on different conditions is made and the key elements influencing system performance are educed
   利用集成a / d 、 d / a轉(zhuǎn)換器的新型芯片aduc824 ，實(shí)現(xiàn)了電流(電壓)采樣?數(shù)據(jù)處理?電流控制的閉環(huán)控制結(jié)構(gòu)；地電位的抬升解決了a / d轉(zhuǎn)換器對(duì)負(fù)高壓回路電流采樣時(shí)的輸入范圍匹配問題；控制信號(hào)反相的同時(shí)進(jìn)行幅度壓縮，使得輸出調(diào)整電壓的分辨率提高；根據(jù)常規(guī)的比例?積分?微分( pid )調(diào)節(jié)模型，針對(duì)陀螺系統(tǒng)的特性，給出了一種可以滿足系統(tǒng)要求、據(jù)采樣值偏差大小進(jìn)行的比例?大步長積分?小步長積分、分層次比例?積分算法；不同條件下系統(tǒng)穩(wěn)流性能的對(duì)比、分析在論文最后給出，并據(jù)此找出了決定該系統(tǒng)穩(wěn)流精度的關(guān)鍵因素，提出了系統(tǒng)的改進(jìn)意見。
