Hey everyone,
I am having trouble with PID control of a gas flow.
Basically I have a pipe (shown as 2D ax) where air flows through it. A heater at the middle of the pipe (domain 2) heats the air to the set point of 70C.
I have the comsol file attached that works which shows the air getting heated. But i want to implement PID control. I tried following the PID reactor control example in the documentation, but can't get it to work. I'm trying to control the temperature of the air by the heat source amount. But if there is another easier way, let me know.
Attached are two files: 1, working heater example. 2, not working...but with attempted PID functions.
Any help would be GREATLY appreciated.
