The rotational speed of dc timing control method can be divided into two categories, namely excitation control method with the armature voltage control method. This paper mainly studies the dc speed regulation system, it mainly consists of three parts, including parts, power control, direct current motor. For a long time, the dc motor because of its adjustment speed is more flexible, simple method and so on, have been occupied dominant position in the field of transmission.In this paper, the double closedloop irreversible dc PWM speed regulating system, a further study from the principle of dc adjusting system, gradually establish a closedloop dc PWM adjustment model of the system.正文 雙閉環(huán)可逆直流脈寬PWM調(diào)速系統(tǒng)設(shè)計(jì)設(shè)計(jì)分析雙閉環(huán)調(diào)整系統(tǒng)的傳動(dòng)系統(tǒng)結(jié)構(gòu)圖 直流PWM控制系統(tǒng)是直流脈寬調(diào)制式調(diào)速控制系統(tǒng)的簡(jiǎn)稱，與晶閘管直流調(diào)速系統(tǒng)的區(qū)別在于用直流PWM變換器取代了晶閘管變流裝置，作為系統(tǒng)的功率驅(qū)動(dòng)器，系統(tǒng)構(gòu)成原理圖如下所示：直流PWM傳動(dòng)系統(tǒng)結(jié)構(gòu)圖其中屬于脈寬調(diào)制調(diào)速系統(tǒng)主要由調(diào)制波發(fā)生器GM、脈寬調(diào)制器UPM、邏輯延時(shí)環(huán)節(jié)DLD和電力晶體管基極的驅(qū)動(dòng)器GD和脈寬調(diào)制（PWM）變換器組成。模擬式脈寬調(diào)制器本質(zhì)為電壓脈沖變換裝置，它是由一個(gè)運(yùn)算放大器和幾個(gè)輸入信號(hào)構(gòu)成電壓
