A quad-rotor unmanned aerial vehicle is an under-actuated
strong coupled nonlinear system with parameters uncertainty and unknown external aerodynamic disturbance. 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.

In order to eliminate the influence of aircraft attitude angle to the image quality of space camera
and assure that the drift angle of space camera could be accurately adjusted at the orbit
a novel closed-loop test method is provided for real-time drift angle adjustment of space camera on the Earth. A long focal length dynamic aim generator is applied to simulate the image motion and the variety drift angle
and to detect the precision of the image motion compensation machinery and the capability of the drift angle control system. The computer system is used to control the dynamic aim generator
accomplish the data processing
transmit and receive the data information. The seamless connection and the data transmission between the aim generator and the aircraft simulation devices are constituted. The command
parameter and drift angle data transmitted by the simulation devices are received by the space camera at the real time
then the photos are taken and the draft angle is adjusted simultaneously. It is shown that the drift angle can be accurately tracked by the space camera at the real time
and the detective method satisfies the test requirement. 2010 Copyright SPIE - The International Society for Optical Engineering.
