error "Wire: is a member of a cycle

Bill, 

I dont think you understood what I was trying to say. I would be grateful to u if you read my query and then reply. I am having error due to the direct feed through behavior exibited by the transfer function, it doesnt make any change how many times I rewire the system.

😞 I have a new problem  all the wires are closed now,but when I run the vi the control variables are going in some random function(nowhere near setpoint ). I know the controller and this configuration is working because i got a good response for the same in Matlab,but I want to do it in Lab VIEW. i have given a feedback node as BEn62 suggested and initialised it to zero. Any possible suggestions for this ?

0 may be too far from the setpoint for the system to converge. Try initializing the FB node with a value closer to the setpoint.

You're right.  I assumed you mistakenly wired something incorrectly, not that you actually believed it was wired correctly and that it was LabVIEW that had the issue.
