CAA Intelligence Sets Sail for a Shared Future2021 rings in the 60th anniversary of the founding of the Chinese Association of Automation (CAA). As an important social force, the CAA has contributed to the cause of development of the automation science and technology in China in a steadfast and unremitting manner. Over the past 60 years, automation, information and intelligent science and technology have undergone earth-shaking changes, constantly changing the way of life of human beings and leading the socioeconomic development.

To celebrate the 60th anniversary of the CAA, the English official account launches the "Automation Terms" column introducing automation-related terms every day, so as to contribute to the popularization of automation knowledge.

Chinese：比例控制English：Proportional ControlDefinition：控制器的输出值与被控参数的测量值和设定值或某个参考点的偏差是一个比例关系比例控制比二位控制要平滑一些，消除了二位控制时会产生的被控量上下振荡的情形。

比如，对一个反应罐的液位，如果设定的液位值是2700毫米，当液位降低时，进料管道上的阀门就要增加开度，而液位偏高时，则要将开度减小增加和减小的比例与液位和设定值的偏差大小成比例关系Term Example:

Proportional control is a control system technology based on a response in proportion to the difference between what is set as a desired process variable (or set point) and the current value of the variable. 

比例控制是一种控制系统技术，它基于设定为期望过程变量(或设定值)与变量当前值之间的差的比例响应。Source：bingNew media channels of the CAA
