The trajectory tracking control system with a nested double-loops structure is designed in this paper according to the coupling characteristic between the attitude angles and translational position. A PD control algorithm is proposed in the translational outer-loop to export the desired attitude signals to the attitude inner-loop. An adaptive backstepping control algorithm is designed in the inner-loop with respect to the uncertain rotational inertia and un-modeled disturbance  while in order to reduce the computational complexity the command filtered approach is introduced into the designing procedure. And finally  the numerical simulation results are presented for the trajectory tracking stabilization of a Quad-rotor  which demonstrates the excellent performance of the proposed control system and illustrate its robustness in face of disturbance and uncertain parameters. 2012 IEEE.   Robust trajectory tracking control of autonomous quad-rotor UAV based on double loop frame (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Materials, Mechatronics and Automation, ICMMA 2011, January 15, 2011 - January 16, 2011, Melbourne, VIC, Australia 作者:  Sun Q. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 This paper deals with the under-actuated characteristic of a quad-rotor unmanned aerial vehicle (UAV). By designing the double loop configuration  the autonomous trajectory tracking is realized. The model uncertainty  external disturbance and the senor noise are also taken into consideration. Then the H controller is put forward in the inner loop. An optimal stability augmentation control (SAC) method is used to stabilize the horizon position and keep it away from oscillation. By calculating the nonlinear decouple map  control quantity is converted to the speeds of the four rotors. At last some simulation results and the prototype implementation prove that the control method is effective.
