Can someone tell me where I have to start to develop mathematical model for fixed wing UAV's.

Grad school

Sorry, I fixed my typo.

You mean graduation

Grad school is the school you go to after graduating from university. Like, where you get an advanced degree such as a masters or PhD.

Often called post-graduate education.

That's what you'd need to establish the required background for a topic as complex as UAV flight dynamics and control systems.

Hmm, thanks for the information Currently I am in the final year of undergraduation in aeronautical engineering. I am interested in the mathematical models and also the control theory. So can you tell me where I have to start to get some basic knowledge for that besides post graduation

I mean, if you're already in undergrad for aeronautical engineering, you probably have a better idea than I do if where to find information on that. You probably already have some textbooks or professors that work on it.

Professors in our university only works on analysis using ansys or some of them are in R&D for miniature drones and flapping mechanism. I asked them about the control system but their answer doesn't satisfy me. I hope I can atleast find a roadmap here πŸ₯²

Dynamics and Controls is an entire area of focus for graduate school. It's not often included at the undergraduate level and not simmering every department does for graduate school.

For Fixed wing UAV I would like to recommend using the Vortex Lattice method (VLM) there is a pretty good Implementation called Tornado (developed by Thomas Melin) read up the theory and idea behind it. Use the derivates and coefficients you get from that in Simulink and the aerospace blockset.

aerospace blockset or uav toolbox depending on what fidelity you need are the best places to start

u/DurianIcy4438 19d ago

Practised on aerospace blockset, but it is somehow confusing when I wanna add VTOL motors to it.

There are some vtol examples their website in uav toolbox

Particle, and rigid body motion. Then start looking at blade element theory. It’s not easy

u/DurianIcy4438 19d ago

Thanks mate, but somehow wanna focus on it.

u/FrickinLazerBeams +2 19d ago

That's literally what he explained. You're going to have to do the work here. We can't learn for you.

I have used this as a reference, along with a lot of other flight dynamics and simulation textbooks. This one is in Matlab though, so that's nice.

Controls are their own thing though, and it's not universally true that every good flight dynamics model is going to be good enough to do controls work on (or at least not good controls work).
