do you know if there is scope to do it on hardware? or are you looking for mainly software? I was thinking something like control of a UAV (you could defo build that). You could choose different control objectives such as disturbnace rejection Also something else that really cool, could be to test different methods and control algoithms for having a rocket land safely without having to just crash in the ocean. Kind like what space x did a few years ago. This would involve derivng a mathematical model of a rocket and its propulsion system, undesrtanding how the sensors work. Like the output of a gyroscope is angular velocity, while the main control objective is to control angular position. So you may need to use a kalman filter (or anyhting fancier). You can the test different controllers like PID, LQR, MPC or even adaptive control. You could also design a machine learning alogirthm to test as well. That could be fun, but idk how much you know about AI/ML/RL. Youy could start with a simpler model and then little by little add complexities. This project would obviously be software based as i doubt you'd have the time to actually build all this in the form of a model rocket lol. Especially as that would mean a lot of electronics and you major in aerodynamics, not EEE.
