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.

This article is the study of alternating stress of flexible wheel in harmonic gear drive system. Firstly
then
Finally
according to elasticity theory to theoretically analyze flexible wheel stress
based on the basic principle of sub-structure modal synthesis method
based on the dynamics simulation
use the software of UG
to analyze the alternating stress simulation results of flexible wheel and compare theoretical results and simulation results to come conclusion. The results show that: altering stress simulation results of flexible wheel are coincident with theoretical simulation results
PATRAN and ADAMS to carry out co-simulation
have a deeper understand the stress change trend in the drive process of flexible wheel
lay a foundation for further carrying out dynamics simulation of harmonic gear drive system. (2012) Trans Tech Publications

The objective of this paper is to deal with a trajectory tracking of a Quad-rotor unmanned aerial vehicle (UAV). For the model uncertainty
the external disturbance and the coupling factor are considered
an active disturbance rejection control (ADRC) algorithm is introduced into the designing procedure. The aircraft dynamic model is proposed in this article
based on which the closed-loop control system is divided into four independent channels with the coupling factor compensated by the extended state observer (ESO). The nonlinear state error feedback (NLSEF) algorithm is designed in each channel to improve the closed-loop dynamics. In this article
the ADRC controller is expressed in the discrete form. And finally
the simulation results show that the proposed control algorithm achieves a favourable tracking performance. 2012 IEEE.

The reliability flight property has received much attention within the aircraft control community throughout the last decades. In this paper
the fault-tolerant control technique is introduced into the attitude stability control system of a quadrotor UAV in order to compensate the influence of the actuators fault of the aircraft. This control scheme is composed of two components: a robust fault detection module using the modelbased observation approach and a reconfigurable controller. Besides the designing procedure
the theoretical analysis of robustness and stability of the designed FTC scheme are also contained in this article. And finally
the availability of the proposed scheme is verified through numerical simulation. 2012 IEEE.
