Fault- Tolerant Polynomial Smoother and Fault-Tolerant Differential Smoothers

基于滑动多项式平滑与多项式微分平滑 ,建立了两组能够有效控制故障数据影响的滑动递推容错滤波与容错平滑算法。仿真计算结果证实 ,本文建立的容错平滑与容错微分平滑算法对跟踪测量系统的突变型故障具有良好的容错能力。

A series of sliding polynomial smoother and differential smoother are given in this paper.Two improved fault- tolerant approaches are propozed,and some simulation are made.The simulation results show thatthese fault- tolerant approaches are able to prevent bad influence from outliers or pulse- type fault in tracking process
