Set-membership algorithm for identification of structural parameters based on ARMA time-series model

  • 摘要: 研究在时域内利用含噪声观测数据识别结构参数问题.建立了与结构振动微分方程等价的自回归滑动平均(ARMA, Autoregressive Moving-Average)时序模型,将结构参数识别问题转换为ARMA模型参数辨识问题.在不确定但有界(UBB, Unknown-But-Bounded)噪声假设下,基于线性时不变系统参数集员辨识的区间算法,寻求与观测数据和噪声相容的参数的最小超长方体(或区间向量),进而得到结构参数的估计值.通过数值算例,将本文算法与最小二乘算法进行了比较,显示了其可行性和有效性.
