| 中文摘要 |
| 在本文中，将具有不同类型故障的线性系统都用带偏差的线性状态方程来描述，偏差的跳变表现了故障。结合偏差分离估计法与统计决策原理，导出了用于故障检测与估计的修正偏差分离估计方法，该方法简单直接，且不需故障的任何验前信息。树枝仿真结果表明，该方法能可靠地检出故障和精确的估计出故障的大小。 |
| 英文摘要 |
| In this paper , the linear system with failure is described as the linear state equation with bias, the failure is expressed by the abrupt change of bias. A modified separated-bias estimation method for failure detection and estimation is proposed by combining the separated-bias estimation method and the statistical decision principle. This method is very simple and the prior knowledge about failure is not necessary. The simulation shows this method can detect reliablely the failure and estimate accurately the failure magnitude. |
