基于DOB和二自由度控制器的某火炮稳定控制系统设计

火炮稳定控制系统性能会受到如路况、火炮射击时产生的冲击力矩等外部扰动以及摩擦力矩变化、测量噪声、转动惯量变化等内部参数摄动的影响。针对此问题,引入一种DOB观测器和二自由度控制算法,来减少摩擦对系统性能的影响,提高系统对载体扰动的隔离能力。仿真和实验结果表明,所提出的算法可以有效提高系统的稳定精度和速度伺服性能。     

基于作战任务的舰艇数据链传输时效控制方法

数据链作为舰艇信息系统的重要组成部分,其效能的发挥程度直接影响作战任务的完成度。针对舰艇数据链技战术运用缺乏科学化、规范化理论支撑的问题,创新性地将作战任务完成度理念引入到舰艇数据链传输时限判定和实效性管控过程中,通过构建舰艇作战任务完成度量化评估模型,并详尽分析数据链传输实效判定因素,提出了基于作战任务的舰艇数据链传输时效性管控方法。     

基于复杂网络的作战同步建模与优化

为了量化分析作战同步问题,提出多作战单元协同作战复杂网络模型,在此基础上,应用复杂网络同步理论,重点从作战单元动力学行为和网络拓扑结构两个方面对作战同步的内在机理进行分析。针对不同的作战情形,设计了静态同步和动态同步两种网络,并分别应用离散粒子群算法对网络结构进行优化。对网络抗毁性的仿真实验表明两型网络对随机攻击和恶意攻击均具有较好的鲁棒性。     

基于AHP的射手综合素质的三级模糊综合评判

针对装甲机械化部队射手素质评价存在的评价内容不全、指标选取不合理等诸多问题,提出了一种基于层次分析法(AHP)和模糊评价法的射手综合素质的三级模糊综合评判模型。首先,在对射手综合素质深刻剖析的基础上,建立了射手综合素质评价指标体系,并运用层次分析法确定了各指标权重;然后,运用模糊综合评价法构建了射手综合素质的三级模糊综合评判模型;最后,通过实例验证了该模型的科学性与实用性。

Defensive weapons and star wars: a supergame with optimal punishments

We model the perspective faced by nuclear powers involved in a supergame where nuclear deterrence is used to stabilise peace. This setting allows us to investigate the bearings of defensive weapons on the effectiveness of deterrence and peace stability, relying on one-shot optimal punishments. We find that the sustainability of peace is unaffected by defensive shields if the latter are symmetric across countries, while asymmetric endowments of such weapons have clear-cut destabilising consequences.     

The lobbies’ network at the EU policy level: the case of security and defense

Lobbyists may not share the same interests, but they usually agree to form a link in a network which could eventually be used to spread information, to search for potential partners, to speak with one voice to decision makers. In other words, social links represent value for lobbyists because they may ultimately facilitate access. In this article, we explore the network of the Security and Defense lobbies in the EU and we describe its structure.     

The relevance of the Gulf of Guinea in global energy politics

Africa and for that matter the Gulf of Guinea cannot be indifferent to the global energy politics of the 21st century. The increasing importance of the region has attracted major actors in the energy sector. The competing interests of these actors are played out in various forms. This heightened interest in the region, especially with the discovery of oil in huge commercial quantities, has brought the importance of the area into focus in global oil politics. This paper looks at the importance of the region in light of the huge energy potentials of the Gulf of Guinea and how the institution of proper governance systems could serve as an important factor in ensuring the proper management of the resource.     

Reserve forces and the transformation of British military organisation: soldiers,citizens and society

In recent years, there has been a sharp growth in political and sociological interest in the British military. Set against the backdrop of the armed forces’ increasing presence in everyday life, alongside the organizations’ ongoing restructuring, the current paper focuses on the MoD’s problematic attempts to recruit 30,000 reservists by 2020; what has become known as the Future Reserves 2020 programme (FR2020). We argue that these changes are driven in part by the need to cut costs in defence. However, we also suggest that they are a reflection of the changing nature of modern military organisation, and the manner in which armed forces engage with the societies of which they are a part, and with the citizens that make up that society. We locate FR2020 programme in the context of a wider narrative about the changing nature of military organisation in contemporary western democracies, identifying structural, circumstantial and normative reasons for change. We also examine the specific challenges of implementing FR2020 in practice, including issues of recruitment and retention, integration and support, and relations with families and employers, drawing on the experience of comparator countries to do so. We conclude by considering the implications of these changes, both for the future of UK armed forces, and for the evolving nature of military-society relations in Britain.     

Strategic hedging in Indonesia’s defense diplomacy

With the rapid pace of regional arms modernization and unresolved territorial disputes, Indonesia is increasingly susceptible to the impact of emerging great power rivalry in Asia-Pacific. Rather than pursuing a robust military build-up, Indonesian policy-makers assert that diplomacy is the country’s first line of defense. This article argues that defense diplomacy serves two agenda of Indonesia’s hedging strategy – strategic engagement and military modernization. This way, Indonesian defense and security officials seek to moderate the impact of geopolitical changes while maintaining the country’s defensive ability against regional uncertainties.
