style="text-indent:25px">液壓伺服控制系統(tǒng)的工作特點(diǎn)有哪些呢？上海樸魯液壓技術(shù)有限公司小編介紹，液壓伺服控制系統(tǒng)的工作特點(diǎn)有：系統(tǒng)的輸入信號(hào)的功率很小，而系統(tǒng)的輸出功率可以達(dá)到很大。因此它是一個(gè)功率放大裝置，功率放大所需的能量由液壓能源供給，液壓試萬(wàn)能試驗(yàn)機(jī)供應(yīng)費(fèi)用，液壓試萬(wàn)能試驗(yàn)機(jī)供應(yīng)費(fèi)用，供給能量的控制是根據(jù)伺服系統(tǒng)偏差大小自動(dòng)進(jìn)行的。液壓伺服控制系統(tǒng)的工作原理就是流體動(dòng)力的反饋控制。即利用反饋連接得到偏差信號(hào)，再利用偏差信號(hào)去控制液壓能源輸入到系統(tǒng)的能量，液壓試萬(wàn)能試驗(yàn)機(jī)供應(yīng)費(fèi)用，使系統(tǒng)向著減小偏差的方向變化，從而使系統(tǒng)的實(shí)際輸出與希望值相符.伺服液壓系統(tǒng)在該點(diǎn)是穩(wěn)定的，在其它點(diǎn)必然是穩(wěn)定的。液壓試萬(wàn)能試驗(yàn)機(jī)供應(yīng)費(fèi)用</p><div

style="text-indent:25px">伺服液壓系統(tǒng)與電氣伺服系統(tǒng)相比有三個(gè)優(yōu)點(diǎn)：①體積小，重量輕，慣性小，可靠性好，輸出功率大；②快速性好；③剛度大(即輸出位移受外負(fù)載影響小)，定位準(zhǔn)確。缺點(diǎn)是加工難度高，抗污染能力差，維護(hù)不易，成本較高。液壓伺服系統(tǒng)本質(zhì)上是一種非線性控制系統(tǒng)。其非線性因素有：閥的壓力流量特性，由庫(kù)侖摩擦和閥的正重疊量引起的死區(qū)特性，由伺服閥控制窗口的形狀引起的非線性增益，由傳動(dòng)間隙等因素造成的游隙非線性和飽和非線性特性等。其中以游隙非線性特性的影響較為嚴(yán)重，容易使系統(tǒng)產(chǎn)生自激振蕩。液壓試萬(wàn)能試驗(yàn)機(jī)供應(yīng)費(fèi)用伺服液壓系統(tǒng)液壓執(zhí)行機(jī)構(gòu)傳動(dòng)平穩(wěn)、抗干擾能力強(qiáng)。</p><div
