How can I use the Control Design & Simulation module in the Mobile (PDA) modul?

Hi everyone!

I have to create Bode and Nyquist plot from Transfer function on a PDA, but I can't use CD&S Modul when I'm opening a new Mobile project.

Thank you for your answer!

Sincerely yours,

Does it have to any transfer function? Or is it some limitations

[Jenő Kocsis]

This is a limitation.

I have to do something like the Attachment on a PDA.

Replace s with jx2xpixfreqency. Then use complex math functions in Labview. Vary the frequency and calculate enough points to draw the plots. Then use the Complex To Polar Function for drawing the bode plot. The r is the magnitude and theta is the phase. theta is in radians! Plot this values against the frequency. I am not sure for the Smith plot. But it is something in the same alley

I'm trying it, hope it'll work.

Thank you!

Hi I have some questions regarding eq3 and eq4. Which one is the feedback loop, and is it positive or negative feedback? Since you have a feedback loop you must take this into account. 

[Jenő Kocsis]

That file was just an example.

Btw eq3 and eq4 are in a parallel connection so not a feedback, there is a little + sign.

 I've made this bode plotter, please, can you check it?

[Jenő Kocsis]

I've made the VI, but there is an error. The cut-off point is'nt there, where is should be.

There is a 10e-1 dislocation.

Please post your equation;) 

[Jenő Kocsis]

Which equation? My equation is in the attached vi.
