UUD148AE01  控制系统  可以获得更好的控制性能

型号：UUD148AE01

3BHE014185R0001 UUD148AE01 ABB控制系统是一种先进的工业自动化控制系统，控制系统是由控制主体、控制客体和控制媒体组成的具有自身目标和功能的管理系统。通过控制系统，人们可以按照所希望的方式保持和改变机器、机构或其他设备内任何感兴趣或可变的量。控制系统的目的是使被控制对象达到预定的理想状态，并使其趋于某种需要的稳定状态。

UUD148AE01控制系统根据不同的分类标准有多种类型。按控制原理分类，可以分为开环控制系统和闭环控制系统。开环控制系统是指系统输出只受输入的控制，没有反馈环节；而闭环控制系统则是建立在反馈原理基础之上，利用输出量同期望值的偏差对系统进行控制，可以获得更好的控制性能。

另外，按给定信号分类，UUD148AE01控制系统又可以分为恒值控制系统、随动控制系统和程序控制系统。恒值控制系统是指给定值不变，要求系统输出量以一定的精度接近给定希望值的系统；随动控制系统则是指给定值按未知时间函数变化，要求输出跟随给定值的变化；程序控制系统则是给定值按一定时间函数变化。

Model: UUD148AE01

3BHE014185R0001 UUD148AE01 ABB control system is an advanced industrial automation control system, the control system is composed of control subject, control object and control media with its own goals and functions of the management system. By means of a control system, one can maintain and change any amount of interest or variable within a machine, mechanism, or other device in a desired manner. The purpose of the control system is to make the controlled object reach a predetermined ideal state, and make it tend to a certain stable state.

There are many types of UUD148AE01 control systems according to different classification standards. According to the classification of control principle, it can be divided into open loop control system and closed loop control system. Open-loop control system refers to the system output is only controlled by the input, there is no feedback link; The closed-loop control system is based on the feedback principle, using the deviation of the output with the expected value to control the system, can get better control performance.

In addition, according to the given signal classification, the UUD148AE01 control system can be divided into constant value control system, follow-up control system and program control system. Constant value control system refers to the system which requires the output of the system to be close to the given desired value with a certain precision. The servo control system means that the given value changes according to the unknown time function, and requires the output to follow the change of the given value. In program control system, the given value changes according to a certain time function.
