1.This course includes the history of control, modeling of physical processes, design specifications in the time domain,design using the root locus, frequency response and anintroduction to state space design for single-input and single-output systems.
1.本課程主要內(nèi)容包括控制理論的歷史、物理過程的模塊化方法、時(shí)域系統(tǒng)的設(shè)計(jì)方法、用根軌跡法的設(shè)計(jì)方法、頻率響應(yīng)，以及單一輸入/輸出系統(tǒng)狀態(tài)方程設(shè)計(jì)方法的介紹。

2.In 1945 H. W. Bode presented a system for analyzing the stability of feedback systems by using graphical methods. Until this time, feedback analysis was done by multiplication and division, so calculation of transfer functions was a time consuming and laborious task.
2.1945年HW伯德提出了一套系統(tǒng)方法，用圖形化方法來分析反饋系統(tǒng)的穩(wěn)定性。在此之前，反饋分析是通過乘法和除法完成的，所以傳遞函數(shù)的計(jì)算是一項(xiàng)費(fèi)時(shí)和費(fèi)力的任務(wù)。

3.Remember, engineers did not have calculators or computers until the '70s. Bode presented a log technique that transformed the intensely mathematical process of calculating a feedback system's stability into graphical analysis that was simple and perceptive.
3.請記得工程師們在上個(gè)世紀(jì)70年代之前是沒有計(jì)算機(jī)或者計(jì)算器的。伯德提出了一種日志技術(shù)，這種技術(shù)將計(jì)算反饋系統(tǒng)穩(wěn)定性這種復(fù)雜的數(shù)學(xué)過程轉(zhuǎn)換為簡單和直觀的圖像分析。

4.Feedback system design was still complicated, but it no longer was an art dominated by a few electrical engineers kept in a small dark room.
4.反饋系統(tǒng)的設(shè)計(jì)雖然還是很復(fù)雜，但它不再是幾個(gè)電氣工程師待在一個(gè)小黑屋里的藝術(shù)了。

5.Any electrical engineer could use Bode's methods find the stability of a feedback circuit, so the application of feedback to machines began to grow. There really wasn't much call for electronic feedback design until computers and transducers become of age.
5.任何電氣工程師都可以使用伯德的方法找到一個(gè)反饋電路的穩(wěn)定點(diǎn)，因此反饋電路在機(jī)器中的應(yīng)用開始增加。直到計(jì)算機(jī)和傳感器的時(shí)代到來之前，反饋電路的設(shè)計(jì)真的沒有太多的要求。
