摘要
通过研究多级运载火箭飞行全过程,搭建包括多级运载火箭仿真数据产生器、数字回波产生器、模拟目标跟踪系统、精度评估系统在内的半实物仿真平台,采用基于IMM框架的多模型选择算法进行模拟跟踪实验,得到一组匹配参数,将实测数据作为半实物仿真平台数据输入,进行算法验证。仿真结果表明,基于IMM框架的多模型选择算法具有鲁棒性高、跟踪无滞后的特征,适于工程实际应用。
A semi-physical simulation platform is constructed,including a multi-stage carrier rocket simulation data generator,a digital echo generator,an analog target tracking system,and an accuracy evaluation system through studying the entire flight process of multi-stage carrier rockets.The multi-model selection algorithm is used based on the IMM framework for simulation tracking experiments,obtaining a set of matching parameters.Furthermore,actual measured data are input into the semi-physical simulation platform to validate the algorithm.The simulation results indicate that the multi-model selection algorithm based on the IMM framework features high robustness and lag-free tracking,and is suitable for practical engineering applications.
