Intelligent actuator receives the output signal from the regulator and compares it with valve position feedback signal and obtains output signal which is directly proportional to the output signal of regulator according to the deviation between the signals and then control the pneumatic actuator 智能执行器接受调节器的输出信号,在与阀位反馈信号进行比较,然后根据两者的偏差产生和调节器输出信号成正比例的输出信号控制执行器。
