The control system development will ultimately be done in Simulink, where we will build and simulate the quadcopter model, tune the controller, test it in a closed loop simulation, and finally automatically generate flight code that we will load into the onboard micro controller on the Parrot minidrone. INTRODUCTION This paper is based on the attitude control of a quadcopter with external disturbances. The adaptive control is an advance control technique which provides a systematic approach for automatic adjustment of controllers in real time, in order to achieve or to maintain a desired level of control system performance, when the parameters of the plant dynamic model are unknown and/or change in time . However, in the simpliﬁed dynamic model, we eliminated the Euler angles and kept only translational quantities. I have few questions about it. You need to get your hands dirty. It needs a control system and angular sensor data for continuous stabilization during flight. In order to do this I need to put the linearized differential equations in this form: $$ \dot{x} = Ax + Bu $$ $$ y = Cx $$ 3 Realizing position control of the Parrot AR.
