In fluid dynamics, angle of attack (alpha) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow. Since controlling this angle is very important in this project it subjected as propose of controlling loop.

First of all, a f-16 aircraft modelled by a vast number of article and paper which every one are emphasize just a part of the system. Tis system consist of 5 state like height, angles, speed and son on. Then, it stability point detected which is very valuable in chosing control algorithm.

Second, modern control method especially LQR method used to optimize error and actuators force/tourqe. As illustration, observer and controller are simulated through Matlab software. The observer was worthwhile wich use half data in order to predict situation of aircraft.

Finally, result of simulation and optimization of control coefficient presented as a project report.
