temperature controller

[Matt V]

Hi gents,

I'm trying to make a temperature controller, but no succes till now.. When you run the vi you will see a blue line and a red line in het Waveform graph, the red line is now showing a random temperature. I want to try to make a controller, so the red line will come close to the blue line. The data for the blue line is loaded from an other document, also attached. Can somebody help me? Thanks in advance!

Regards Matt V

ps excuse for my English

Do you have the Control Simulation and Design module?   The PID vi's will do what you want.  You will have to do some tuning to get the PID parameters set.  There are many threads on this forum about temperature control.

No I don't have that module, working on Labview 2011 SP1.. Could not find anything in the forum about this. You think it will work without that module?

You would have to write your own PID algorithms. I really recommend getting the module.

My search came up with several posts on temperature control:
