4、零漂
在閉環(huán)控制過(guò)程中，零漂的存在會(huì)對(duì)控制效果有一定的影響，將其住。使用控制卡或伺服上零飄的參數(shù)，仔細(xì)調(diào)整，使電機(jī)的轉(zhuǎn)速趨近于零。由于零漂本身也有一定的隨機(jī)性，所以，不必要求電機(jī)轉(zhuǎn)速為零。
5、建立閉環(huán)控制
再次通過(guò)控制卡將伺服使能信號(hào)放開(kāi)，在控制卡上輸入一個(gè)較小的比例增益，至于多大算較小，這只能憑感覺(jué)了，如果實(shí)在不放心，就輸入控制卡能允許的值。將控制卡和伺服的使能信號(hào)打開(kāi)。這時(shí)，電機(jī)應(yīng)該已經(jīng)能夠按照運(yùn)動(dòng)指令大致做出動(dòng)作了。
6、調(diào)整閉環(huán)參數(shù)
細(xì)調(diào)控制參數(shù)，確保電機(jī)按照控制卡的指令運(yùn)動(dòng)，這是必須要做的工作，而這部分工作，更多的是經(jīng)驗(yàn)，這里只能從略了。

2.直流電機(jī)的勵(lì)磁方式是指對(duì)勵(lì)磁繞組如何供電、產(chǎn)生勵(lì)磁磁通勢(shì)而建立主磁場(chǎng)的問(wèn)題。根據(jù)勵(lì)磁方式的不同，直流電機(jī)可分為下列幾種類型。
1．他勵(lì)直流電機(jī)
勵(lì)磁繞組與電樞繞組無(wú)聯(lián)接關(guān)系，而由其他直流電源對(duì)勵(lì)磁繞組供電的直流電機(jī)稱為他勵(lì)直流電機(jī)。永磁直流電機(jī)也可看作他勵(lì)直流電機(jī)。
2．并勵(lì)直流電機(jī)
并勵(lì)直流電機(jī)的勵(lì)磁繞組與電樞繞組相并聯(lián)，接線如圖（b）所示。作為并勵(lì)發(fā)電機(jī)來(lái)說(shuō)，是電機(jī)本身發(fā)出來(lái)的端電壓為勵(lì)磁繞組供電；作為并勵(lì)電動(dòng)機(jī)來(lái)說(shuō)，勵(lì)磁繞組與電樞共用同一電源，從性能上講與他勵(lì)直流電動(dòng)機(jī)相同。
3．串勵(lì)直流電機(jī)
串勵(lì)直流電機(jī)的勵(lì)磁繞組與電樞繞組串聯(lián)后，再接于直流電源，接線如圖（c）所示。這種直流電機(jī)的勵(lì)磁電流就是電樞電流。
4．復(fù)勵(lì)直流電機(jī)
復(fù)勵(lì)直流電機(jī)有并勵(lì)和串勵(lì)兩個(gè)勵(lì)磁繞組，接線如圖（d）所示。若串勵(lì)繞組產(chǎn)生的磁通勢(shì)與并勵(lì)繞組產(chǎn)生的磁通勢(shì)方向相同稱為積復(fù)勵(lì)。若兩個(gè)磁通勢(shì)方向相反，則稱為差復(fù)勵(lì)。

一進(jìn)房屋，門(mén)起著非常重要的作用;一方面它增加美麗和優(yōu)雅。而另一方面，它提供了安全，對(duì)于動(dòng)物，甚至是氣候條件。門(mén)作為增強(qiáng)外觀和給人的印象，所以一個(gè)人必須非常小心和有選擇性的，選擇家里的每一道門(mén)。各種門(mén)在市場(chǎng)的材料以木材，鋼材，金屬和玻璃之間的范圍。幾年前，木門(mén)是因?yàn)樘峁┙o消費(fèi)者在市場(chǎng)上，也由于木材的自然外觀，擁有非常多的趨勢(shì)。然而，隨著不斷變化的時(shí)尚，木門(mén)流下自己的美麗，隨著時(shí)間的推移暴露在惡劣的天氣條件。

南方地區(qū)梅雨季節(jié)的氣候比較潮濕，給人們?nèi)粘Ｉ顜?lái)了許多困擾。家里地面回潮，墻壁滲水，中老年人開(kāi)始腰酸背痛，風(fēng)濕性關(guān)節(jié)炎患者倍感煎熬，人們的心情也會(huì)因潮濕而變得壓抑，這時(shí)候如果家里有一臺(tái)除濕機(jī)，這些煩惱便可一掃而光。據(jù)了解，家庭設(shè)計(jì)制造的除濕機(jī)其小巧省電實(shí)用，為居室創(chuàng)造清爽舒適的生活空間，成為現(xiàn)代家庭的又一新寵。除濕機(jī)一般由壓縮機(jī)、熱交換器、風(fēng)扇、盛水器、機(jī)殼及控制器組成，運(yùn)行時(shí)由風(fēng)扇將潮濕空氣抽入機(jī)內(nèi)，通過(guò)熱交換器將空氣中的水份冷凝成水珠，再將干燥的空氣排出機(jī)外，如此循環(huán)反復(fù)使室內(nèi)濕度不斷降低。
