Hi
I'm using a PID loop to control gas pressure. I understand that the setpoint is the value that is required (1000Kpa in my case). The process variable is the value that is being measured by the pressure sensor that I have. However what I dont unederstand is how do I use the control output? I need to reduce or increse the pressure of the system using 2 PWMs (1 for increasing and 1 for decreasing pressure). How do i specifically use the control output to do this? Is it as simple as saying if output < 1000 then open PWM 1 and if its > 1000 then open PWM2??
Thanks so much in advance
