I am interested in building a rocket with feedback control system.... so I have been interested in model rocketry lately and I was wondering how feasible it would be to design and build a model rocket for my senior project complete with a control system to ensure it flies straight up. I was considering using two fins with adjustable flaps to control the rotation of the rocket about its axis and 4 fins to control the angle of the rocket. 2 fins would be used to control each of the two components. I would require 3 independent feedback systems. One feedback system for ensure the rocket does not rotate about its axis, 1 feedback system to control the 'x component' of the tilt of the rocket and another feedback system to control the 'y component' of the tilt. The rotation angle, x component, and y component will be controlled to a value of zero. This rocket will be designed to go straight up only. How feasible would this project be? I know I would need access to a wind tunnel that could simulate aerodynamic drag and cross wind effects. Also, I would need to beef up on my control systems. I would want to use digital control systems, but I am a little weak in this subject.
