Closed loop circuit 閉環(huán)電路
Based on the fault tree analysis ( fta ) , the main loop circuit of electrical life - test device is studied and its corresponding fault tree constructed 在故障樹分析理論的基礎(chǔ)上,對電壽命試驗(yàn)設(shè)備的主回路進(jìn)行了分析,并建立相應(yīng)的故障樹。
The method is to judge whether a system is stable by analyzing the amplification of loop circuit based on amplitude frequency response and phase frequency or not 這種方法是將電路的幅頻特性和相頻特性曲線結(jié)合起來對環(huán)路增益進(jìn)行分析,以此作為判斷系統(tǒng)是否穩(wěn)定的依據(jù)。
This paper suggests that there is another better way to judge whether a system is stable or not - that is analyzing the amplification of loop circuit with the nyquist rule 由于激勵信號是復(fù)數(shù)形式的變化量,因此我們還可以采用奈奎斯特準(zhǔn)則,利用奈奎斯特圖在復(fù)平面上的變化特點(diǎn),對環(huán)路增益進(jìn)行分析。
