智能气动阀门定位系统动态特性研究
Research on dynamic characteristics of intelligent pneumatic valve positioning system
摘要
Abstract
A mathematical model is proposed for the implementation of the digital twin of the intelligent pneumatic valve positioning system,which can accurately simulate the action mechanism of the pneumatic relay and the actuator gas chamber and the dynamic characteristics of the gas.In the case of no gas mass flow meter,the pneumatic relay dy-namics model and the equivalent mass flow model with variable diameter throttle plate are established as a function through theoretical derivation and experiment,the multivariable process of the actuator gas chamber is modeled,and the digital twin of the positioning system is implemented.The system is verified to be reliable through the actual operation test of the digital twin as well as model simulation and experimental comparison.关键词
