| 摘 要： | 针对所有的基于粒子滤波的动态数据校正中粒子滤波方法仅仅是针对数据的,本文提出了一种基于粒子滤波和过程模型的动态数据校正方法(DDRPFPM)。该方法将过程模型引入到动态数据校正中,作为约束条件来更新粒子的权值,有效提高了粒子的信任度,解决了基于粒子滤波的动态数据校正(DDRPF)过程中存在的粒子退化问题。通过CSTR仿真证明,DDRPFPM能够较好的应用于动态数据校正,与DDRPF相比无论是对温度噪声还是离群值都有更强的校正能力。

| Abstract: | To solve the problem of all the dynamic data rectification method based on the particle filters just consider the data,a novel dynamic data rectification rriethod based on particle filters and process models(DDRPFPM) is proposed here.The process models is introduced into dynamic data rectification,and the constrained conditions of process models are used to update the weight secondly,in this way,particle's confidence is improved and the degeneracy problem of particles in the dynamic data rectification based... |
