Application of taguchi's method to binary distillation column simulation results

good day all. having obtained data after the simulation of a binary distillation column in VBA using a P,PI,PD,PID controller, i intend to design a very simple experiment with these data using a taguchi's orothgonal array. i've read the taguchi method extensively but can't still figure out how to apply it to my simulation results. please all suggestions is most welcomed.many thanks!
