State-space model or transfer functions of drone


I am trying to create a controller to pilot the Anafi autonomously from a python script. I’m first trying to model the behavior of the drone in MATLAB so I can determine performance characteristics of my drone. Since olympe only provides the moveTo and PCMD commands for drone control, I’ve been looking for mathematical models of the drone with reference to the change in axis tilt (i.e. pitch, roll, yaw, altitude). I have so far not been successful in finding anything like a state-space model or transfer functions.
I’ve already checked MATLAB, parrot documentation, parrot support, research papers, and a million forums so I figured I’d come ask here.
Any documentation or a point in the right direction would be great!
