This paper applied spintronic memristors on the neural network PID controller to control the nonlinear and time-varying buck converter. The proposed method used spintronic memristor as electronic synapses to store the updated value, which can greatly simplify the implementation of hardware circuit and the weights updating algorithm. Meanwhile three-layers memristor-based BP neural network was designed and the algorithm of the PID control under this mechanism was also analyzed. Furthermore, computer simulation of buck converter working in continuous mode with the proposed controller presented superior performance in the aspects of follow-up, immunity and robustness, as well as fast response and small overshoot.

A harvested predator-prey system with Holling type II functional response and a constant prey refuge is proposed. Compared with other researches on dynamics of predator-prey population, this system is described by differential-algebraic equations due to economic factor. By choosing m as bifurcation parameter and using the new normal form of differential-algebraic systems, center mainfold theorem and bifurcation theory, we get the stability and the Hopf bifurcation of the proposed system. We believe the new effective analytical method here enriches the toolbox for the qualitative analysis of the differential-algebraic systems. Finally, numerical simulations illustrate the effectiveness of our results.

In this paper, variable structure control is combined with nonlinear Active-Disturbance Rejection Control (ADRC) for ship's track keeping control under the influence of internal dynamic uncertainties and external disturbances. In this way the needed setting parameters are greatly reduced with no change of the intrinsic controller's advantages. Meanwhile through the design of dimension reduction equation, ship's track keeping control can regarded as a desired head following control. Simulation results show that the new controller is robust against the systemic variations and external disturbances, and owns preferable control effect, which can realize the accurate track keeping.

To explore the influence on interpolation results in different models of ordinary kriging interpolation methods and to validate their feasibility in practice, the interpolation experimental study using Spherical, Exponential and Gaussian models were carried out in this paper, based on the monthly average Air Quality Index data of 10 air quality sites in Wuhan, China. The interpolation results were qualitatively analyzed and quantitatively evaluated by the actual render effect and cross-validation method. The experimental results demonstrate that: (1) for the same data, the visual render effect in different models are almost the same in the whole, but the interpolation accuracies are different; (2) the Mean Standardized error and Root-Mean-Square error of the Spherical model are the largest; (3) the Mean error of the Exponential model is minimal, the Root-Mean-Square error is nearest to Average Standard Error, and its Root-Mean-Square Standardized error is closest to 1; (4) the Mean error of the Gaussian model is the largest, but both Mean Standardized error and Root-Mean-Square error are minimal, the Root-Mean-Square error is farthest away from Average Standard error, and also its Root-Mean-Square Standardized error is farthest away from the value 1.

Monitoring coastline change is a significant task of coastal zone management and evolution research, and it is an important symbol for the study of the regional change of reclamation area. Remote sensing technology becomes an important approach of monitoring changes in the coastline by virtue of its high efficiency, wide range and low cost. Taking the Beidaihe coast as an example, the coastline extraction of SAR and Landsat TM images is extracted based on the geometrical active contour model. This method through setting the initial contour, regards the movement of contour curve as synthesize of force, and minimizes the energy function. It makes the initial contour approximate to the real object boundary. The result shows that the method can effectively extract the continuous and complete coastline from different kinds of remote sensing images.

Direct yaw moment control can maintain the vehicle stability in critical situation. For four-wheel independently driven (4WD) electric vehicle with in-wheel motors (IWMs), direct yaw moment control (DYC) can be easily achieved. A fairly accurate calculation of the required yaw moment can improve vehicle stability. A novel sliding mode control (SMC) technique is employed for the motion control so as to track the desired vehicle motion, which is it for different working circumstances compared to the well-used traditional DYC. Through the weighted least square algorithm, the lower controller is used to determine the torque properly allocated to each wheel according to the desired yaw moment. Several actuator constraints are considered in the control strategy. In addition, a nonlinear tire model is utilized to improve the accuracy of tire lateral force estimation. Then, simulations are carried out and the values of vehicle states are compared. The simulation results show that the control system proposed can effectively improve the handling stability of the vehicle.

In this paper, we develop an intelligent overtaking decision-making method for highway autonomous driving. The key idea is to use reinforcement learning algorithms to learn an optimized policy via a series of simulated driving scenarios. A vehicle model based on data fitting of real vehicles as well as a traffic model is established to simulate driving scenarios and validation tests of obtained policies. Human driving experiences are considered in designing the reward function. A reinforcement learning method called the Q-learning algorithm is used to learn overtaking decision-making policies. Simulations show that our method can learn feasible overtaking policies in different traffic environments and the performance is comparable or even better than manually designed decision rules.
