该文提出一种基于智能海洋捕食者算法的模型预测控制策略,实现了波浪能转换装置的动态最大能量捕获。提出的模型预测控制策略利用海洋捕食者算法来获取最优控制力,并采用非线性限制来控制功率的单向流动。通过相应的对比分析验证了海洋捕食者算法的优化准确性和快速收敛性。该方法还利用控制域来处理最优控制变量以便在算法的计算负担和优化准确度之间进行平衡。所提出的方法证明在处理多维的波浪能转换系统方面,特别是系统的非凸和非线性限制问题,具有较好的利用价值。仿真与实验结果证明提出的方法能较好地提高波浪能转换装置的输出功率,并满足典型海域工况下的实时需求。

The addition of electrolyte additives is an effective strategy for tuning the property of the electrolyte to engineer the electrode/electrolyte interface,and there exist obvious discrepancies regarding the effect of fluoroethylene carbonate(FEC)as an electrolyte additive on the performance of *** FEC is introduced into the electrolyte of the LiMn_(0.8)Fe_(0.2)PO_(4)/Li cell and its effect on the properties of the LiMn_(0.8)Fe_(0.2)PO_(4) is *** is found that the addition of FEC in the electrolyte has a positive effect on the performance of the LiMn_(0.8)Fe_(0.2)PO_(4) cathode,which can be attributed to the reduced products generated by the interfacial side-reactions on the LiMn_(0.8)Fe_(0.2)PO_(4) cathode surface and the decreased metal dissolution in the FEC-containing electrolyte,thanks to the higher oxidation resistance of FEC and the easier and stronger binding of FEC and PF_6^(-).

Surface charge distribution of particles is the fundamental problem for adsorption and desorption between sediment and contaminant. In this paper, we take quartz sand for example to measure its micro-morphology and surface charge distribution using the phase mode of the electrical force microscope. Then the statistical relation of micro-morphology and surface charge distribution is obtained. Results show that quartz sand possesses complex surface morphology, which has great impact on the charge distribution. Positive and negative charges mostly concentrate on the saddle, convex and concave parts of the surface, while distribute less in the groove, ridge and flat parts. This experiment provides a new method for understanding the process of flocculation in coastal and estuarine zone.

Suspended movement is supported by eddy of river. In this paper the turbulent stochastic regularity of flow and sediment was adopted and the settling model of the suspended movement was established. Then, stochastic regularity of the sediment in sedimentation basin was investigated. The calculating results were compared with measured data. The results are in good agreement and the calculating method is very simple. The divided diameter of washload and bed material load was discussed from the relation of turbulent intensity and sediment settling velocity.
