摘要：文章首先介绍了用于空间合作卫星最后逼近段交会对接任务的仿真平台,描述了文中使用的姿态运动学方程和视觉成像算法。为了充分利用陀螺仪和视觉系统进行姿态确定,采用传统的扩展卡尔曼滤波(EKF)对两种测量数据进行融合,实现对姿态和陀螺仪漂移的估计。为了克服EKF调节参数过多和计算过程需要求逆的问题,设计了一种新的非线性观测器。最后,通过在对接仿真平台上进行试验,对比验证了非线性滤波器的有效性以及实用性。

摘要：自主创新能力意识的培养,是当前研究生教育中的重要课题。如何在知识传授、技能培养与能力锤炼的同时,有计划、有步骤地提升研究生的自主创新能力,是国内多数高校面临的一个难点问题。文章在上海电机学院专业硕士课程《大数据技术》的授课过程中发现,课程思政加持下的课堂在自主创新能力培养上至少存在以下三点不足,分别是学生理想观念弱、破冰理念低、专注能力差。文章在前期调研基础上,提出了以危机意识、创新意识与献身意识为核心的思政框架,并通过“直面问题,创新突破,砥砺前行”的思路,设计课堂内容。数据显示,此举能更大程度地调动学生的积极性,学生的自主创新能力在量化指标上得到了明显提升。The cultivation of independent innovation ability awareness is an important issue in current graduate education. How to systematically and systematically enhance the independent innovation ability of graduate students while imparting knowledge, cultivating skills, and honing abilities is a difficult problem faced by most domestic universities. During the teaching process of the professional master’s course “Big Data Technology” at Shanghai Dianji University, it was found that there are at least three shortcomings in the cultivation of independent innovation ability in the classroom under the support of ideological and political education, namely weak ideal concepts, low ice breaking concepts, and poor focus ability of students. Based on preliminary research, this article proposes an ideological and political framework with crisis awareness, innovation awareness, and dedication awareness as the core, and designs classroom content through the idea of “facing problems directly, innovating breakthroughs, and forging ahead”. The data shows that this move can more effectively mobilize the enthusiasm of students, and their independent innovation ability has been significantly improved in quantitative indicators.

摘要：对弹道导弹中段多目标拦截中任务分配模型建立进行了研究。给出了目标分配优化模型,分析了温度、位置与速度、雷达散射面积(RCS)等因素对目标威胁程度的影响,给出了目标威胁度的定量描述,基于模糊聚类和粗糙集理论设计权重分配,建立了评价目标威胁程度和拦截有效程度数学模型。用算例进行定量分析,验证了构建的模型的可行性和有效性。讨论了存在目标转移时的分阶段目标分配以及时间协同制导在任务分配中的必要性。
