Hi everyone,
I am trying to make a vi to control proportional valve for gas filling into a vessel at a desired pressure. I have just prepared a trial vi for this task, however, I am not sure about the coefficient and also the vi. I have feedback from a pressure transducer (0-10 bar) which generates voltage signal between 0-10V. According to this feedback I have to control the proportional valve. As far as I know valve gate opening and the pressure inside the vessel must be the reversely related to each other. To adjust the valve gate opening, how can I set the PID vi parameters? You can see the vi that I prepared in the attachment.
