基于AFSA的自抗扰控制器参数整定

自抗扰控制器（ADRC）的参数众多,通常依赖于人工试凑优化,控制系统的性能好坏过分取决于设计人员的经验且效率不高。针对ADRC的参数选取问题,首次利用鱼群算法（AFSA）全局寻优能力强,鲁棒性好的特点,结合已有的参数整定经验,提出了一套基于AFSA的ADRC参数整定规则,并进行了数字仿真。仿真结果表明,经由基于AFSA参数整定规则优化过后的ADRC具有良好的动静态特性,提高了设计效率,验证了该方法的可行性和有效性。     

互联网中文搜索引擎存在的问题与发展趋势探析

搜索引擎是互联网信息检索技术的核心,中文搜索引擎与国外相比存在着搜索引擎覆盖率低、查准率不高、检索精度差、更新速度慢、无法控制网络信息的动态变化、对信息内容难于控制和管理等问题。对此,提出了中文搜索引擎从单一查询工具向综合化、全功能服务发展;分类主题一体化,检索语言向自然语言发展;查询智能化,向多国化和多语种化发展;搜索引擎集成化、网络资源著录标准化及利用智能代理技术的信息检索等对策。

Military intelligence and the war in Dhofar: An appraisal

This article examines the role military intelligence played in the Dhofar campaign between 1970 and 1976. Drawing on an array of sources, it examines not only the crucial role played by military intelligence in prosecuting a successful operational campaign against a Marxist inspired insurgency, but equally, the importance that intelligence played in consolidating the Al Bu Said dynasty when across Oman and Dhofar itself, the material benefits to be had from the discovery and production of oil had yet to be realised.

Saddam versus the inspectors: the impact of regime security on the verification of Iraq’s WMD disarmament

The discovery that Iraq had no weapons of mass destruction (WMD) in 2003 raised the question of why Saddam had prevented UN weapons inspectors from fully accounting for his disarmament. The leading explanation for Saddam’s behavior is that he valued ambiguity as part of a strategy of ‘deterrence by doubt’. This article argues that Iraq’s obstruction of inspectors in the late 1990s was motivated by his desire to shield Iraq’s regime security apparatus from UNSCOM’s intrusive counter-concealment inspections. The failure to understand how strongly Saddam’s concerns about his personal safety drove Iraq’s contentious relationship with UNSCOM set the stage for the invasion of Iraq in 2003.
