Transfer Function of the Voice Coil Motor
How to construct the transfer function of a voice coil motor?


I am trying to construct a control system with MATLAB/SIMULINK that including a voice coil motor(VCM). But i have no idea what a VCM transfer function look like. It would be great if anyone can provide me a real example of a VCM transfer function.

Any information will be appreciated.
Thank you for your time.
