smith predictor

Is it possible in Labview to demonstrate the stability criteria [Bode, Nyquist etc.] for the Smith Predictor.  Given that the Smith Predictor block diagram is functionaly a closed loop within a closed loop, but Bode, Nyquist etc are all based on the open loop response of the system.

Sample vi is attached for info.

Hi,

 

It looks like other people have tried similar things before- the following links are all forums with code attached which it may be worth taking a look at?
