Yesterday I took my master's degree in Aerospace engineering with thesis of the video below.
I'm Italian and my english in not the best. Could you review all text in the video and the description below? Thanks!
This video is a summary of my master's degree thesis in aerospace engineering took inside Università degli Studi di Palermo (Italy).
Rockets spin about their longitudinal axis due to an imperfect realization. This behavior could be a problem for telemetric systems or when guidance control on the other two axes are used.
In my thesis I designed, made and tested an automatic control system to wipe out the roll angular speed of a model rocket.
The system uses two control fins (aerodynamic control) moved by a flight computer equipped with a 3DOF gyroscope, an accelerometer and an atmospheric pressure sensor. I entirely made this flight computer: electronics, printed circuit and programming in C language. The code contain also two digital Kalman filters which compute an optimal estimation of the state-space from sensor data.
To design the digital controller and to predict the dynamic behavior of the entire rocket I implemented in Matlab / Simulink a 6 degree of freedom mathematical model. All aerodynamic parameters where estimated with real test flight or with McDonnell Douglas Digital DATCOM Fortran code (program which uses semi-empirical methods).
I also designed and realized the rocket motor from a commercial combustion chamber.
