由于工業(yè)現(xiàn)場的工作境往往十分惡劣，計算機控制系統(tǒng)不可避免地受到各種各樣的干擾。這些干擾可能會影響到測控系統(tǒng)的精度，使系統(tǒng)的性能指標 下降，降低系統(tǒng)的可靠性，甚至導致系統(tǒng)運行混亂或發(fā)生故障，進而造成生產(chǎn)事故。干擾可能來自外部，也可能來自內(nèi)部；它通過不同的途徑作用于控制系統(tǒng)，且其作用程度及引起的后果與干擾的性質(zhì)及干擾的強度等因素有關(guān)。干擾是客觀存在的，研究抗干擾技術(shù)就是要分清干擾的來源，探索抑制或消除干擾的措施，以提高計算機控制系統(tǒng)的可靠性和穩(wěn)定性。干擾使指有用信號以外的噪聲或造成計算機設(shè)備不能正常工作的破壞因素。產(chǎn)生干擾信號的原因稱為干擾源。干擾源通過傳播途徑影響的器件或系統(tǒng)稱為干擾對象。干擾源、傳播途徑和干擾對象構(gòu)成了干擾系統(tǒng)的三個因素?？垢蓴_技術(shù)就是通過對這三要素中的一個或多個采取措施來實現(xiàn)的。為了有效的抑制和消除干擾，首先要分清干擾的來源、傳播途徑以及干擾的作用方式。計算機控制系統(tǒng)中干擾的來源是多方面的，有時甚至是錯綜復雜。總體上，按照來源，干擾可分為內(nèi)部干擾和外部干擾。外部干擾與系統(tǒng)所在環(huán)境和使用條件有關(guān)，與系統(tǒng)內(nèi)部結(jié)構(gòu)無關(guān)。內(nèi)部干擾則由系統(tǒng)結(jié)構(gòu)布局、制造工藝等引入。外部干擾：與系統(tǒng)結(jié)構(gòu)無關(guān)，是由使用條件和外部環(huán)境決定的。外部干擾主要有：天電干擾，如雷電或大氣電離作用引起的干擾電波；天體干擾，如太陽或其它星球輻射的電磁波；周圍電氣設(shè)備發(fā)出的電磁波干擾；電源的工頻干擾；氣象條件引起的干擾，如濕度、溫度等；地磁場干擾；火花放電、弧光放電、輝光放電等產(chǎn)生的電磁波等。內(nèi)部干擾：是由系統(tǒng)的結(jié)構(gòu)布局、線路設(shè)計、元器件性質(zhì)變化和漂移等原因造成的，主要有：分別電容、分布電感引起的耦合感應；電磁場輻射感應；長線傳輸?shù)牟ǚ瓷洌欢帱c接地造成的電位差引入的干擾；寄生震蕩引起的干擾以及熱噪聲、閃變噪聲、尖峰噪聲等。
