MATLAB: System Identification

Question

Hey!

I am designing a control system for a bearing system.

Here I have 3 inputs and one output. Can anybody tell me about the system identification of such system.

Regards, mac.

Answer 1

Try estimation functions such as OE, ARX, N4SID and PEM in releases R2011b and older. In R2012a you can also try TFEST, SSEST, PROCEST and POLYEST.

etc...

You will have to indicate what you tried if you want more concrete help.
