Question: How to reduce/approximate an n order transfer function to a second order transfer function

Hi

I have crreated a transfer function of a rather complex system using TransferFunction() and recived a transfercundtion of a rather high order (n=10). However due to the kinematics of the model I know that is is posible to expres as an second order transfer function.

So I have been locking around Maple for a function that can help me reduce or approwqimate the transfer function as a sencond order but I have not found anything.

Is there a way to reduce/approximate an n order transfer function to a second order transfer function?

Mvh
