I'm building a system in Labview 2009 with system and control. This system analyses a step response of a DC motor and determines the discrete transferfunction (I do this with system identification tool in Labview). Then convert de TF to a Zero-pole function. When that is done I want to determine de PID values for this model using the "Design PID for descrete functions" vi block, but the problem is that is doesn't work. I added a screenshot off that part of the program.
If it does work I want to simulate de closeloop TF with PID. And plot a stepresponse (also isn't working).
What I'm a doing wrong or forgetting ?
Could you post your VI here so I can see what you are working with?
What do you mean by "it does not work" when using Design PID for Discrete Functions VI?
