Question: How to plot the Bode plot of this transfer function with Maple 15?

Maple 15

> BodePlot(sys,range=10^(-1)..10^(3));

I get the following warning:
             Warning, transfer-function(s) are not rational-polynomial(s) in s

Why?.. How can I make it work without any warning?

Thanks everybody for help!
