定义：
执行器是自动控制系统中的执行机构和控制阀组合体。它在自动控制系统中的作用是接受来自调节器发出的信号，以其在工艺管路的位置和特性，调节工艺介质的流量，从而将被控数控制在生产过程所要求的范围内。(1) actuators are divided into pneumatic, electric and hydraulic actuators according to the use of the driving energy of the three.
(2) in the form of output displacement, the actuator has two types of angle and linear type.
(3) according to the law of motion, the actuator can be divided into three types: switch type, integral type and proportion type.
(4) according to the input control signal, the actuator can be divided into several types, such as the input air pressure signal, the DC current signal, the electrical connection point break signal, the pulse signal and so on.
