【正文】 cesses between the good speed control and the electric current control relations. After studies and the practice repeatedly, finally discovered, if establishes two regulators in the system, adjusts the rotational speed and the electric current separately, Between both implements the series connection, namely by the rpm control output took current regulator ACR the input, uses the current regulator the output to take the thyristor trigger again the control voltage, then these two kind of control action can coordinate mutually, plemented one another.This paper presents the simulation study of a DC speed regulation system by using the Simulink modules .the result indicates that the system simulation by using MATLAB is convenient and highly effectiveKey Words: The course design of dualclosedloop DC speed regulating system。經(jīng)過(guò)反復(fù)研究和實(shí)踐，終于發(fā)現(xiàn)，如果在系統(tǒng)中設(shè)置兩個(gè)調(diào)節(jié)器，分別調(diào)節(jié)轉(zhuǎn)速和電流，兩者之間實(shí)行串聯(lián)連接，即以轉(zhuǎn)速調(diào)節(jié)器的輸出作為電流調(diào)節(jié)器ACR的輸入，再用電流調(diào)節(jié)器的輸出作為晶閘管觸發(fā)裝置的控制電壓，那么這兩種調(diào)節(jié)作用就能互相配合，相輔相成了。摘要：此課程設(shè)計(jì)實(shí)現(xiàn)了雙閉環(huán)直流調(diào)速系統(tǒng)的設(shè)計(jì)，結(jié)果可以準(zhǔn)確直觀的觀察轉(zhuǎn)速電流雙閉環(huán)調(diào)速系統(tǒng)的啟動(dòng)過(guò)程，可方便的設(shè)計(jì)各種不同的調(diào)節(jié)器參數(shù)及控制策略并分析其多系統(tǒng)性能的影響，取得了很好的效果。進(jìn)一步解決限流問題，唯一的途徑就是對(duì)電流也實(shí)行反饋控制，問題是怎樣處理好轉(zhuǎn)速控制和電流控制之間的關(guān)系。本文利用NATLAB軟件中的sinulink組件對(duì)直流雙閉環(huán)調(diào)速系統(tǒng)進(jìn)行仿真，結(jié)果表明，應(yīng)用MATLAB進(jìn)行系統(tǒng)仿真具有方便，高效及可靠性高等優(yōu)點(diǎn)。 Irreversible system；DC motor。目錄第一章 緒論 ……………………………………………第二章 已知條件及控制對(duì)象的基本參數(shù)…………………………第三章 設(shè)計(jì)方法及步驟………………………………………Ⅰ 用工程設(shè)計(jì)方法設(shè)計(jì) ……………………………………（1）系統(tǒng)設(shè)計(jì)的一般原則……………………………………（2）電流調(diào)節(jié)器設(shè)計(jì)…………………………………………（3）轉(zhuǎn)速調(diào)節(jié)器設(shè)計(jì)…………………………………………………Ⅱ 用調(diào)節(jié)器最佳整定法設(shè)計(jì) ………………………………………（1）電流環(huán)的動(dòng)態(tài)校正………………………………………………（2）轉(zhuǎn)速換的動(dòng)態(tài)校正……………………………………………第四章 利用MATLAB軟件中sinulink組件對(duì)直流雙閉環(huán)調(diào)速系統(tǒng)仿真……………………………………………………………… 第五章 設(shè)計(jì)心得……………………………………………………參考文獻(xiàn)………………………………………………………………
