针对伞翼无人机参数不确定性和复杂环境干扰敏感的问题,提出一种伞翼无人机线性自抗扰(Linear Active Disturbance Rejection Control,LADRC)高度控制方法。建立伞翼无人机8自由度飞行动力学模型,并引入风场和降雨模型以更加准确地模拟真实飞行环境。基于LADRC确定总体控制架构,设计线性扩张状态观测器对所有扰动进行估计,并引入误差反馈率在控制中实时补偿。使用该控制方法在多种扰动工况下进行伞翼无人机高度控制仿真实验。仿真结果表明,基于LADRC的高度控制方法能够有效克服内扰和外扰的影响,实现高精度高度控制;与传统PID控制效果相比,LADRC控制器具有更好的抗扰能力和鲁棒性。 相似文献

This article presents survey data on the African Peace and Security Architecture (APSA). It focuses explicitly on two aspects: the internal constitution and achievements of the APSA; and coordination and cooperation with external actors, such as Regional Economic Communities, the United Nations and the European Union. The survey, conducted between October 2011 and December 2012, targeted 198 security experts in international organisations, think tanks, academia and non-governmental organisations. It reveals the APSA's current stage of development, achievements and challenges. 相似文献

行为在犯罪论体系中具有重要地位,行为概念本身也具有限定、统一和结合的机能。存在论立场得出的概念难以涵纳过失行为和不作为行为,而以价值论为立场得出的概念虽然具有更强的解释力,但缺乏对象性的客体事实,难以实现刑法的保障机能。以存在论和价值论的哲学联系为出发点,以可控制条件说为内核,从事实层面到价值层面建构不同外延的行为概念更有利于发挥行为概念的各种机能,也有利于维护刑法的基本原则,适应理论和实践的需要。 相似文献

Private‐label products are of increasing importance in many retail categories. While national‐brand products are designed by the manufacturer and sold by the retailer, the positioning of store‐brand products is under the complete control of the retailer. We consider a scenario where products differ on a performance quality dimension and we analyze how retailer–manufacturer interactions in product positioning are affected by the introduction of a private‐label product. Specifically, we consider a national‐brand manufacturer who determines the quality of its product as well the product's wholesale price charged to the retailer. Given the national‐brand quality and wholesale price, the retailer then decides the quality level of its store brand and sets the retail prices for both products. We find that a manufacturer can derive substantial benefits from considering a retailer's store‐brand introduction when determining the national brand's quality and wholesale price. If the retailer has a significant cost disadvantage in producing high‐quality products, the manufacturer does not need to adjust the quality of the national‐brand product, but he should offer a wholesale price discount to ensure its distribution through the retailer. If the retailer is competitive in providing products of high‐quality, the manufacturer should reduce this wholesale price discount and increase the national‐brand quality to mitigate competition. Interestingly, we find the retailer has incentive to announce a store‐brand introduction to induce the manufacturer's consideration of these plans in determining the national‐brand product quality and wholesale price. © 2010 Wiley Periodicals, Inc.
