Reducing the order of Transfer function

I have an inverse of a tranfer function (TF) matrix. I am using this for my controllers. The inverse TF matrix I have is 6th order. Now I want to reduce the TF to lower orders, maybe to second or third. I have attached the screenshots. Any kind of help is appreciated.

If you have not already used the minreal (link) function, see if it will reduce the order.

Beyond that, I have no specific suggestions other than that you explore the other functions linked to in that documentation page.

Try using 'balred' command. It works well. you can best fit a transfer function of desired order in required frequency range of importance.
