As part of a Uni assignment i have to use the control and simulation package on labview to implement a smith predictor.
I have created a file with shows the plant model on one tab, standard pid loop on the second tab with the option to set a dead delay time & smith predictor on the third tab. I think my code is working fine until i start trying to set the appropriate gain values (PID) the tunning method i am trying to use is the cohen coon method.
I cant get the output to meet the set point no matter what gain value i put in and when i adjust it too many times the program stops displaying it on the PID graph.
I have attached my code to this post. Can someone help advice why the PID graph is not displaying very well on tabs 2 &3 and advice suitable tunning values.
