| 摘 要： | 针对非线性带滑移滞变系统模型复杂，参数多，识别时收敛困难等问题，提出了一种三阶段逐步收敛的识别方法对Baber与Noori提出的带滑移滞变模型进行了参数识别。计算实例表明，该方法具有收敛速度快、且容易收敛的特点，对于参数较多、模型复杂的系统，是一种非常有效的参数识别方法。

| Abstract: | In view of the problems that the models of non linear hysteretic systems with slip are complex and the number of parameters in them is large,a three stage iterative procedure is proposed for the parametric identification of a smoothed hysteretic model with slip proposed by Baber and Noori.The results of simulation show that the proposed approach has the advantages that the convergence is easy and rapid.It is ideally suited for the identification of nonlinear hysteretic systems with slip typically encountered in the applied mechanics field. |
