In this paper, an online receding robust predictive control scheme is proposed for input-constrained semi-trailer system with delay and disturbance. The controller method meets the requirements of control constraint and, based on dual-mode control, the method is obtained by online optimization of performance index. The performance index is the cumulative sum of quadratic weighted value of minimal states. Controller output is calculated by means of linear matrix inequality (LMI), and the controller itself can ensure the asymptotic stability and disturbance attenuation of semi-trailer closed-loop system. Finally, simulation results confirm the effectiveness of the method. © 2014 SERSC.

Model predictive control (MPC) differs from other control methods mainly in implementation of the control actions. In this paper, the tracking error performance index of rolling optimization of predictive control is designed for a class of nonlinear systems by the relative degree, then employed to design controller for robot manipulator. In other words, the robot manipulator's reference trajectory is based on Taylor expansion, and the actual trajectory is substituted into the performance cost function which is derivated for minimum to obtain the controller. Then the performance analysis for the closed system is made. Simulation results demonstrate the effectiveness of the method based on Taylor expansion. © 2014 Kavala Institute of Technology.

By micro-arc oxidation (MAO), the oxide coatings were prepared on the surface of magnesium alloys in a composite electrolytic solution. The microstructures of the coating layer and the interface between coating and substrate were analyzed by using transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The oxide coating consists of two layers (the outer and the inner layer). Although both layers are composed of microcrystalline MgO and amorphous phase, the inner layer is more compact and rich in fluorine with a thickness of about 1-2 μm. Fluorine plays an important role in the inner dense layer formation. The inner layer, like a barrier wall, blocks the thickness of the oxide coating to increase and improves corrosion resistance. The formation mechanism of the inner layer is also discussed. © ASM International.

Using regression analysis is used to NBA 2012-2013 season scoring before 15 tactical capability indexes were statistically analyzed. Through the technical index regression analysis regression prediction model is established, the technical indexes and the independent variables linear combination that scoring standardization and observations of goodness-of-fit better, stronger practicability and maneuverability, which has great significance to the development of inspiration. © 2014 WIT Press.
