電氣控制原理電路設(shè)計(jì)的方法主要有分析設(shè)計(jì)法和邏輯設(shè)計(jì)法兩種。
1、分析設(shè)計(jì)法
分析設(shè)計(jì)法是根據(jù)生產(chǎn)工藝的要求選擇適當(dāng)?shù)幕究刂骗h(huán)節(jié)（單元電路）或?qū)⒈容^成熟的電路按其聯(lián)鎖條件組合起來，并經(jīng)補(bǔ)充和修改，將其綜合成滿足控制要求的完整線路。當(dāng)沒有現(xiàn)成的典型環(huán)節(jié)時(shí)，可根據(jù)控制要求邊分析邊設(shè)計(jì)。
分析設(shè)計(jì)法的優(yōu)點(diǎn)是設(shè)計(jì)方法簡單，無固定的設(shè)計(jì)程序，它是在熟練掌握各種電氣控制電路的基本環(huán)節(jié)和具備一定的閱讀分析電氣控制電路能力的基礎(chǔ)進(jìn)行的，容易為初學(xué)者所掌握，對(duì)于具備一定工作經(jīng)驗(yàn)的電氣技術(shù)人員來說，能較快地完成設(shè)計(jì)任務(wù)，因此在電氣設(shè)計(jì)中被普遍采用；其缺點(diǎn)是設(shè)計(jì)出的方案不一定是最佳方案，當(dāng)經(jīng)驗(yàn)不足或考慮不周全時(shí)會(huì)影響線路工作的可靠性。為此，應(yīng)反復(fù)審核電路工作情況，有條件時(shí)還應(yīng)進(jìn)行模擬試驗(yàn)，發(fā)現(xiàn)問題及時(shí)修改，直到電路動(dòng)作準(zhǔn)確無誤，滿足生產(chǎn)工藝要求為止。
2、邏輯設(shè)計(jì)法
邏輯設(shè)計(jì)法是利用邏輯代數(shù)來進(jìn)行電路設(shè)計(jì)，從生產(chǎn)機(jī)械的拖動(dòng)要求和工藝要求出發(fā)，將控制電路中的接觸器、繼電器線圈的通電與斷電，觸點(diǎn)的閉合與斷開，主令電器的接通與斷開看成邏輯變量，根據(jù)控制要求將它們之間的關(guān)系用邏輯關(guān)系式來表達(dá)，然后再化簡，做出相應(yīng)的電路圖。
邏輯設(shè)計(jì)法的優(yōu)點(diǎn)是能獲得理想、經(jīng)濟(jì)的方案，但這種方法設(shè)計(jì)難度較大，整個(gè)設(shè)計(jì)過程較復(fù)雜，還要涉及一些新概念，因此，在一般常規(guī)設(shè)計(jì)中，很少單獨(dú)采用。其具體設(shè)計(jì)過程可參閱專門論述資料，這里不再作進(jìn)一步介紹。
