Continously tuned PID

[DavidT]

Are there any VI's or examples that would help in programming a PID control loop that would auto-tune itself continously.
I am running Labview 7. Any thoughts would be appreciated.

PID algorithms can be quite complex. Ideally you could make a vi to iterate throught the P, I, and D parameters until you achieve stable control. The 7.0 PRO-DEV Suite example should fill your need.

I am having the same issue, I am using hte simplePID.vi and would like to have it auotmatically tune itself.   Is there an auto tuning PID.vi that I could download, without purachasing the toolkit?  I could not find one in the example codes I have with my labview 7.0

Hello EMERL,

We don't have an example program that does PID autotuning since there is an auto tune VI included in the PID toolkit.  More information on the toolkit and how to use the Auto Tuning VI is linked from the following discussion forum post.

Thanks
