| 摘 要： | 在许多情况下，对于非平稳或性能随时间发生变化的结构，要求对结构的参数进行实时的跟踪与识别，此时传统的递推算法．如卡尔曼滤波等方法就不再适用，而需要采用具有一定跟踪能力的自适应递推算法．本文对自适应卡尔曼滤波方法在时变结构参数估计中的应用进行了分析，并对其跟踪性能进行了探讨．

| Abstract: | In many cases,it is necessary to identify the time variation of system dynamic characteristics of the non-stationary or time-varying structures,and the traditional recursive methods,such as recursive least-squares and Kalman filter cannot be used. A different recursive identification method must be studied to increase the tracking ability. The adaptive Kalman filter and its application to the parameter estimation of time-varying structures were analyzed in this paper and the tracking ability of this method was discussed. |
