Hello...
I need to find transfer function equation by using MATLAB System Identification Toolbox. But in this GUI, I only get polynomial equation.
My question is, how to convert this polynomial equation to transfer function equation?
I already use ARX model and not used Output-Error (OE) for this system identification toolbox.
How can I export identified model into MATLAB workspace?
Can you explain the step to export identified model into MATLAB workspace?
How to run TFDATA command on it to fetch numerator (Num) and denominator (Den) polynomials?
Thanks for your respond...
Thanks a lot...
hope you can help me.. Thanks...
