How to reduce the order of FOPID controller?

I have designed FOPID controller by using Fomcon Toolbox.I transfer
the controller to work space and then it gave me a state space model of
large number of state. Then I used a command modred but its shows the
error that this command is not applicable to system having more zeros
than poles. Can anyone guide me how to reduce its order. I want to 
transfer this controller in labview for practical implementation.
