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.

Mn1 - xCrxTe films with x = 0 0.02 and 0.05 was synthesized by pulsed laser deposition and crystallize in hexagonal NiAs-type structure. The spin glass behavior predicted before by Monte Carlo calculation is observed in the MnTe film. This behavior is destroyed by adding Cr in the MnTe film. The temperature dependence of magnetization shows a sharp rise at around 66 K due to the magneto-elastic coupling. Metallic behavior is observed in the MnTe film in the temperature range 120-220 K which is ascribed to the magnetic ordering. The metallic behavior disappears with adding Cr because adding Cr ions destroys the magnetic ordering which is mediated by the sp-d exchange interaction between the Cr ions. 2012 Elsevier B.V.

In this paper the mathematical modeling and the application of a new trajectory tracking control technique for hydraulic-driven rigid-flexible manipulator are concerned. To get a closer dynamic behavior of the real system both the flexible manipulator linkage and the actuator dynamics are considered. The exact dynamic model of flexible manipulator is derived using Lagrange principle and assumed modes method. The partial decoupled dynamic equation is derived using nonlinear decoupling feedback control method. The whole dynamic model is established by a driven Jacobin matrix which represents the coupling between hydraulic servo system and mechanical system. A variable structure controller with inverse dynamics is designed for trajectory tracking. To weaken the chattering of control signal saturation function is used to instead of sign function. The experimental results investigate the effectiveness of the proposed approaches. 2012 IEEE.

Self-assembly of the sodium molybdate copper chloride and glycine in aqueous solution results in a novel compound {(NaCu(6)(Gly)(8)(H(2)O)(2)][Mo(8)O(26)(GlyH)(2)(Cu(Gly)H(2)O)](2)}{NaCu (6)(Gly)(8)(H(2)O)(2)}{ Mo(8)O(26)(GlyH)(2))center dot 16H(2)O (1). Compound 1 contains a new unit of {[NaCu(6)(Gly)(8)(H(2)O)(2)][Mo(8)O(26)Cu(Gly)(2)I(2)) in which the [Mo(8)O(26)Cu(Gly)(2)] polyoxometalate units are connected by the [NaCu(6)(Gly)(8)(H(2)O)(2)] hexanuclear copper cluster. The magnetic measurement of 1 shows that ferromagnetic coupling exists between the magnetic centers of the hexanuclear copper cluster.

Missile's attitude change will be delivered to visual axis through stabilized platform during maneuvering flight and the missile vibration will be an interference source to visual axis stabilization. In order to solve this problem the coupling relationship between missile attitude and visual axis is obtained by Coordinate transformation. When the seeker stably tracks a target the angular velocity of visual axis in inertial space is zero so the relative angular velocity of roll axis and pitch axis can be derived for servo control. According to Oura dynamics equation the dynamic models of roll axis and pitch axis were established and kinetic equations of two axises were obtained. The dynamic models can provide theoretical basis to developing research of servo control system and structural optimization design of stabilized platform. Finally some measures could reduce the dynamic coupling between the framework was given. 2011 IEEE.
