I have 3 inputs and 2 outputs on my system ,the tool box gives me an estimation of transfer funtion but it gives like 6 transfer function two for each input with the two outpts.I want it as one transfer function with multiple inputs and multiple outputs to use it in controll system.

That sounds surprising. Can you post some code so we can see how you are identifying the model(s)?

A single transfer function can only relate a single input and a single output. For a 2 output and 3 input system, you will get a 2x3 matrix with 6 transfer function. So, the MATLAB output is correct. How to use this result depends on what you are trying to do next.
