| Abstract: |
| This paper presents a new scheme for parameter identification of multi-degree-of-free-dom structural system :AE-EKF method.The new methodology is based on the idea of defer-ential operator transform about measured data and the extended Kalman filter method.It canbe used either for linear parameter system or non-linear parameter system. Results of simula-tion studies indicate that the new method can yield reliable estimates of system parameterseven when the noise level in measurement records are higher. |
