Hi;
I have a problem with the integration of a signal that I need in my custom-made adaptive controller. In this implementation, I have a function that describes the time derivative of a function. Now I need to integrate this function to use it in my controller signal. I am wondering what Labview function block I should use for this purpose. Not to mention, my code need to run in real-time. .
Thank you.

Are you talking about sending this data to your custom device? At this point it sounds like you are developing your own driver. What communication protocol is your custom device built on? GPIB? Serial? TCP/IP?
Generally, communicating with a custom device requires development of a driver which can be very work intensive. Unfortunately it is not something I would be able to help you with directly, but I can let you know how to communicate with it if it uses one of our supported standard communication protocols.
Hope this helps!

where are you planning to integrate this signal?n LV?

hi SERDARSOYLU
to integrate ur function you can use the mathscript node RT or formula node to implement ur function & then u can utilize it for ur adaptive control, if u will face timing issues then u can use simulation loop with it but both u can do if ur using LAbview 2009 sp1 or latest version
hope it will work

I am going to build a full state feedback control design which is used in real time control, so integrator block is necessary so I have used 1/s block to integrate. But it gives faulty result. How can I use correct result by this block?

Hi Bikash,
You might want to start a new thread to ask your question. In the new thread, make sure to state what you are sending into the node, the specific name of the node (I'm guessing the Laplace Transform Real.vi?) and state what you get out of the node and why it is faulty.
