id控制的意義中英文翻譯資料(完整版)
【正文】 例，當(dāng)一臺(tái)真正的全自動(dòng)洗衣機(jī)具有能連續(xù)檢查衣物是否洗凈，并在洗凈之后能自動(dòng)切斷電源，它就是一個(gè)閉環(huán)控制系統(tǒng)。還有可以實(shí)現(xiàn) PID控制功能的控制器，如Rockwell 的Logix產(chǎn)品系列，它可以直接與ControlNet相連，利用網(wǎng)絡(luò)來(lái)實(shí)現(xiàn)其遠(yuǎn)程控制功能。一個(gè)控制系統(tǒng)包括控制器、傳感器、變送器、執(zhí)行機(jī)構(gòu)、輸入輸出接口。 faster control system response is fast, usually the rise time to quantify.4, PID control principles and characteristicsIn engineering practice, the most widely used regulator control law is proportional, integral, differential control, referred to as PID control, also known as PID regulator. PID controller has been developed for nearly 70 years, it is its simple structure, stable, reliable, easy to adjust and bee one of the main techniques of industrial control. When the structure and parameters of the object and can not fully grasp, or lack of accurate mathematical models, control theory is difficult to use other technologies, the system controller structure and parameters must rely on experience and onsite missioning to determine, when applied PID control technique is more convenient. That is, when we do not fully understand a system and the controlled object, or can not be an effective means of measurement to obtain system parameters, the most suitable PID control technology. PID control, in practice there are PI and PD control. PID controller is the error according to the system, using proportional, integral, differential calculation of the volume control to control. Proportion (P) controlProportional control is the most simple control method. The controller39。 The significance of PID controlThe current level of industrial automation industries to measure the level of modernization has bee an important symbol. Meanwhile, the control also experienced the development of the theory of classical control theory, modern control theory and intelligent control theory of three stages. Intelligent control is a typical example of fuzzy automatic washing machine. Openloop control system can be divided into control systems and closedloop control system. A control system including controller, sensors, transmitters, actuators, input and output interfaces. Controller39。s output and the input error signal proportional. When only a proportional control system output when there is steadystate error (Steadystate error). Integral (I) control In integral control, the controller39?？刂破鞯妮敵鼋?jīng)過(guò)輸出接口、執(zhí)行機(jī)構(gòu)，加到被控系統(tǒng)上；控制系統(tǒng)的被控量，經(jīng)過(guò)傳感器，變送器，通過(guò)輸入接口送到控制器。開(kāi)環(huán)控制系統(tǒng)開(kāi)環(huán)控制系統(tǒng)是指被控對(duì)象的輸出(
