简介：基于排斥粒子，过滤器(MPF)被交上的一个算法在这篇论文详细说明解决太空船态度评价问题：用偏导的旋转罗盘和向量观察的态度和旋转罗盘偏爱评价。在这个算法，由外面排斥在太空船模型的线性地的州的出现，Kalman过滤器与每个粒子被联系以便减少州的空间和计算负担的尺寸。态度向量的分发被一套粒子接近并且估计了使用粒子过滤器，当旋转罗盘偏爱的评价被使用Kalman过滤器为一个态度粒子获得时。这个修改MPF评估者的效率通过充分激活的僵硬身体的数字模拟被验证。为比较，unscentedKalman过滤器(UKF)也被用来计量MPF的表演。在这份报纸介绍的结果清楚地证明MPF比在应付非线性的模型的UKF优异。关键词态度评价-粒子过滤器-太空船-非线性的过滤器-四元数这个工作被研究资金支持因为中国(号码20050213010)的高等教育的博士程序，国家高技术研究和开发中国(863程序)(号码2004AA735080)编程序。刘亚秋加入了信息的学院，东北林地大学，哈尔滨，中国自从2004，他当前在哪儿副教授。他收到了B.Eng的度。(电力工程)电的Technolog从哈尔滨开创M.Eng。(控制理论和工程)从从在1990，1999和2004的哈尔滨工学院的东北林地大学和博士(航行，指导和控制)分别地。他的研究兴趣包括进程控制，聪明的控制和软计算，差错诊断。是的江学元论文的一个相应作者，收到了B.Eng的学位。(自动控制)，M.Eng。(控制理论和工程)并且从在2000，2002和2006的哈尔滨工学院的博士(航行，指导和控制)分别地。他的主要研究兴趣在太空船态度控制，态度评价，和非线性的过滤器。马光富是在学院航天学的一个完整的教授，哈尔滨工学院，哈尔滨，中国，自从1997。他收到了B.Eng的学位。(自动控制)，M.Eng。(控制理论和申请)并且�
