I have a problem with simulation in Matlab 6.5 and LabVIEW for PID controllers

[Lascarica]

I have a problem with simulation in Matlab 6.5 and LabVIEW. I have some methods for granting PID controllers in MATLAB to go but not LabVIEW. International Teams degree to transfer two but when I go past the fourth degree no longer work. We changed the formula for calculating the parameters for grade four and gave me some good values for Matlab award but when I put on LabVIEW have not settled. formulas are available in PDF and are. Please help me and me someone if possible. Thanks
lim.4 generation parameters in MATLAB program and comparison methods are for second-degree transfer function.

Hello Lascarica,

I noticed that you are using the PID VIs. The gains on those VIs are based on TIME instead of GAIN. You should be able to construct a PID controller and vary the gains then compare the results.

OK, I tried something but is not working because I'm a beginner. I thought to make it as implemented in Matlab but not working. Where to look for an example or something, an idea? Thanks!

Hello Lascarica,

Could you explain a bit more on the issue? Are you seeing different responses with the same PID Gains? Could you provide VIs and screen shot to demonstrate your issue?

As for examples, if you launch NI Example Finder > Toolkits and Modules > PID and Fuzzy Logic Control > PID > General PID Simulator VI could be a good reference.

This is the VIs what i try to make,but is not work. This pdf. document was used to create last VIs PID. thenk you for your colaboration.
