I am a little confused as to what you are asking. You asked for "how to implement controller on this" Are you trying to run this VI on a Fieldpoint Controller? Also, it doesn't look like your VI got attached when you posted. If you could provide more information as to what you are trying to do and what the problem is I might be able to help.

I have one typical controlers question where I am using feedback control alongwith compensators. My transfer function is like fourth order TF = 1/S^2(S^2+2) but rootlocus and transfer function in labview do not let me write equation more than 3rd order.
How can I write this 4th order equation.
Next I want to make one feedback control on this transfer function and then want to plot bode and rootlocus.
I have made one vi of fourth order by placing transfer function in series and then for feedback gain I have placed another transfer function with feedback. I have also attached rootlocus vi but it does not show me rootlocus since rootlocus Vi can not take more than fourth order transfer function. I want to plot my step response, bode, and root locus for step input
I have also tried to make another VI with tansfer function VI which has feed back terminal in it, but I donot know how to get bode and rootlocus out of that.
