This is for all you engineers out there! I am currently a graduate student studying mechanical engineering and working on a project for a control systems class involving a UAV. We are in need of a good dynamic aircraft model that we could use as a basis to test various controllers. Basically, we are looking for a state space model/transfer function for a 6-DOF aircraft. Is there anything out there? Or are these sorts of things developed on an as needed basis? Currently we do not have anything resembling an aircraft dynamics class so this is all relatively uncharted territory for us. I know this question is kind of weird, but I would greatly appreciate any help any of you might be able to lend us here!!! Thanks!
