【摘要】 本文研究分布参数系统的辨识问题．要点是先将描述系统的偏微分方程变换到频域上后，化 为第一类Ｆｒｅｄｈｏｌｍ积分方程，然后用逐次逼近法求其数值解，从而确定该系统的物理参数．文中 以一维的剪切梁为例，叙述了基本步骤，并通过模拟计算，检验了该法的有效性．该法通用性较 广，便于实际应用．更多还原

【Abstract】 An iterative numerical method is presented for estimating parameters in system identification and design. One-dimensional beam model is used to test the feasibility and to study the general characteristics of this technique. It has been -found that this method is quite efficient and versatile for engineering problems.更多还原
