【正文】 到所期望的速度。 閉環(huán)控制系統(tǒng) 從反饋比較中得到系統(tǒng)動(dòng)態(tài)的準(zhǔn)確的輸入結(jié)果，一個(gè)不精確的探測(cè)器來說，對(duì)于不同的輸入和輸出，得到一個(gè)成比例關(guān)系的信號(hào)，直到閉環(huán)控制系統(tǒng)等于輸入或誤差為零時(shí)得到輸出。 開環(huán)控制系統(tǒng) 開環(huán)控制系統(tǒng)代表了控制裝置的一種簡(jiǎn)單形式，圖 位控制系統(tǒng)，我們希望使液位保持在合理的可能的范圍，即使通過變量 V1，泄露量一直在變化，這種狀態(tài)是通過變量 V2 的輸入流量速度，或容器 的液位。一個(gè)控制系統(tǒng)是由許多元件以一種方式連接在一起的集合，這種方式能夠影響系統(tǒng)運(yùn)行中占主導(dǎo)作用方面的控制。 controlsystem for ships and submarines, and automatic control systems for hydrofoil, surfaceeffect ships, highspeed rail system。 and most recently, control system for the magiclevitation rail systems. Yet all these types of control, if they are to be successful, have certain features in mon. A control system is the collection of ponents connected in such a way as to effect control over certain aspects of the domain in which the system operate. In addition, Control systems exist that require no human interaction, such as aircraft automatic plots and automobile cruise control system. In dealing with control system, particularly engineering control system, we will deal with a variety of ponents, indicating that the subject is an interdisciplinary one. The control engineer needs a working knowledge of mechanics, electronics, electrical machines, fluid mechanics, thermodynamics, structures, material properties, and so on. Computers are used widely to implement control schemes, and an increasing knowledge of information technology and software engineering is therefore being demanded of control engineers. Obviously not every control system contains elements form each of the above domains but most useful control system contain elements form more than one discipline. In general, control systems can be categorized as being either openloop or closedloop. The distinguishing feature between these two types of
