| Abstract: | Based on the sliding LS filters educed in this paper, a series of practical algorithms are built for detecting outliers and repairing these bad data. By combing the repairing process with filtering, some algorithms of fault tolerant sliding filter with excellent fault tolerance are built. Simulation results show that the algorithms given in this paper have the capability to overcome bad influence coming from outliers properly. |
