矩阵变换器自抗扰控制策略研究

矩阵变换器的输出电压易受各种因素的影响,为了改善输出性能,将自抗扰控制技术应用于矩阵变换器的闭环控制中。分析了自抗扰控制器的特性,提出了一种双闭环自抗扰控制策略,即电流内环与电压外环均采用一阶简化的自抗扰控制算法。仿真结果表明:该方法不仅可以有效地抑制多种扰动的影响,而且比PI控制具有更优的动静态性能,可满足高性能矩阵变换器系统的控制要求。

基于战例数据的制胜要素选择方法

针对战争制胜机理定量研究需求,提出了一种基于混合评估的制胜要素选择算法。针对战例数据特点,该算法选择两种过滤方法分别从不同方面对要素全集进行评估排序而后加权得到综合排序结果;将结果作为遗传算法的初始种群,而后以分类精度作为个体适应度函数。选择几种典型的分类器综合比较,筛选出规模较小、性能较好的要素子集。测试结果表明,该算法不仅能有效地减少要素子集规模,还可以进一步提高制胜机理分析模型的准确率和效率。     

The limits of robotic solutions to human challenges in the land domain

In the face of rapid technological change and the creation of ambitious military modernisation programmes, this paper argues that land forces, in managing the relationship between force levels and the adoption of military robotics, must recognise that there are inherent limits to techno-centric force reduction efforts and realise the inefficacy of substituting skilled soldiers with robots. It begins with an overview of how the proper integration of robotics into a military’s force structure can improve capability, save lives and potentially reduce costs, but suggests that common accounts of robot utility are exaggerated and endanger the risk assessment processes governing the adoption of said technologies and relevant personnel settings. The paper explores the limits of robotic solutions to military problems, discussing their technical limitations, redundancy and related issues that, when combined with a technico-moral skills degradation problem also detailed within, point to the need to reshape force structures to suit the adoption of robotics while preserving existing levels of human staffing.     

Indications and warning in Belgium: Brussels is not Delphi

The terrorist attacks in France and Belgium of 2015–2016 that occurred while these countries were in a heightened state of alert raise questions about indications and warning methodology as well as effectiveness of the blanket-protection deployment of security services assisted even by the military. Response and perhaps even more anticipation may require strategic rethinking in light of the predatory attacks that target the most vulnerable spots of the public space. This study looks at threat analysis in Belgium as conducted through her intelligence fusion centre Coordination Unit for Threat Analysis (CUTA)?????? since its inception in 2006. With a special focus on what is known, at the time of writing, about the terrorist attacks in Paris and Brussels, this study hopes to put into context how the system (mal)functions and will also consider the preventive measures that respond to the threat, and the international aspects which have implications far beyond Belgian borders. Therefore, a case is made for not just a Belgian homeland security framework, but one that fits into an EU-wide security concept.     

Hardening the Hard,Softening the Soft: Assertiveness and China’s Regional Strategy

There is a growing view that the emerging brand of Chinese regional diplomacy in recent years is increasingly assertive. This article attempts to make better sense of this perceived more forceful Chinese diplomacy. It argues that Chinese regional behavior is more profitably understood through the lens of a two-pronged foreign policy strategy that combines two particular aspects. One is a tougher and more uncompromising approach toward issues that China regards as concerning its core interests. The other is a more flexible and cooperative position toward interests that, while significant, are of secondary importance.     

电传动装甲车辆负载功率预测实时能量管理策略

针对电传动装甲车辆负载功率预测功能缺失导致控制作用滞后的问题,提出一种具有较高负载功率预测精度的实时能量管理策略。在分析整车结构的基础上,采用理论分析和数据拟合方法,建立各动力源数学模型。将差分自回归移动平均模型和自适应马尔可夫链两种预测方法相结合,设计非平稳趋势性负载功率组合预测方法。在非线性模型预测控制框架下,构建多目标优化函数,采用序列二次规划法在有限时域内实时求解最优控制指令,优化多动力源协调控制过程。依托硬件在环仿真平台进行多路面行驶实验,对比有无功率预测的能量管理控制效果。结果表明,改进的实时能量管理策略对未来负载功率具有较好的预见性,能够显著优化多动力源协调控制过程,提升车辆燃油经济性,稳定母线电压和电池荷电状态,对传统模型预测控制下的工程应用场景具有一定借鉴意义。
