| 摘 要： | 分析了变化量测及量测闽值等相关概念，提出了变化量测触发方式下的逐次追踪状守估计，每一触发时刻仅对变化量测进行处理。通过算例，对追踪估计有效时段及重启计算问题进行了说明和分析。此方法不但能够明显缩短单次状态估计计算的时间，而且能够保证较高的计算精度，具有实用化的潜力。 |
| 关 键 词： | 状态估计 变化量测 阈值 逐次追踪 |

| Abstract: | Sequential tracing state estimation algorithm under changed measurement triggering mode (CMTM) is presented and the concerned conceptions such as changed measurement and measurement threshold are analyzed. In this algorithm, only changed measurements are handled at every triggering moment. The problem, such as effective period for CMTM state estimation and the restarting computation, are explained via test examples. This method can not only reduce the computation time of a single state estimation, but also guarantee a fairly good estimation precision. It may have the potential of practicability. |
| Keywords: | state estimation changed measurement threshold sequential tracing |
