基于变结构方法的空空导弹鲁棒逆控制律设计

为克服动态逆控制严重依赖被控对象精确数学模型且鲁棒性较差的缺点,将动态逆与变结构方法相结合采用双环结构设计了空空导弹鲁棒动态逆控制律.将导弹飞行状态划分成快慢2个回路,慢回路(外环)采用变结构控制,并设计扩张状态观测器,对外环中的不确定性进行估计;快回路(内环)采用动态逆控制.仿真结果表明,所设计的控制律具有较好的动态特性和鲁棒性能.     

中制导虚拟目标的定位参数研究

基于虚拟目标的优化导引中制导拦截弹道轨迹及其能耗与虚拟目标的位置紧密相关,决定该位置的参数包括中末制导交班距离和视场基准角等.首先研究了弹道特性随定位参数的变化规律并提出通过滚转实现视场基准角的负取值,在此基础上得出满足多约束条件的虚拟目标定位参数的设置方法.利用该方法所产生的虚拟目标与相应的优化导引律结合,可以很好地满足中制导的要求.     

The Demand for Military Spending in Egypt

Egypt plays a pivotal role in the security of the Middle East as the doorway to Europe and its military expenditure reflects its involvement in the machinations of such an unstable region, showing considerable variation over the last 40?years. These characteristics make it a particularly interesting case study of the determinants of military spending. This paper specifies and estimates an econometric model of the Egyptian demand for military spending, taking into account important strategic and political factors. Both economic and strategic factors are found to play a role in determining military burden/spending, with clear positive effects of lagged military burden, suggesting some sort of institutional inertia, plus negative output and net exports effects. The strategic effect as a result of the impact of Israel’s military burden is mostly positive and significant, though its impact is reduced when the impact of important strategic events are taken into account. The military spending of Egypt’s allies Jordan and Syria generally seems to have had no effect on Egypt’s spending. These results are consistent over a range of econometric techniques.     

One size does not fit all: personalized incentives in military compensation

A critical element in implementing a compensation scheme including nonmonetary incentives (NMIs) is recognizing that preferences vary widely across Service members. There are at least three sources of variability: across different population classes, across individuals within a population class, and across NMI packages for a particular individual. Surveys across different military communities, ranks, and years of Service show the difficulty of identifying any NMI that has significant value for even 50% of the active duty force. At the same time, approximately 80% of the surveyed Service members expressed a significant positive value for at least one NMI. Therefore, one-size-fits-all incentive packages will not be nearly as effective as more personalized incentive packages. The authors discuss variability in Service member NMI preferences and outline an approach to implementing personalized NMI packages in military compensation through a sealed-bid reverse auction, where Service members select individual NMIs from a “cafeteria-style” menu of options.     

The United States' retreat from the Middle East and pivot to the Far East is likely to intensify

A combination of threat analysis and “subterranean forces” (such as proclivities to fight conventional wars as compared to asymmetric ones) leads the USA to prefer focusing on the threats from China rather than those emanating from the Middle East.
