| 摘 要： | 本文提出了一种新的分布参数系统的参数辨识方法。该方法通过取状态方程对未知参数的导数而得到灵敏度方程，并用差分求解，通过Newton-Raphson算法辨识未知参数。辨识准则采用输出误差平方最小准则。仿真辨识表明：该方法简捷、概念明确，具有很高的精度和广泛的适用性。

| Abstract: | A new method is presented for estimating parameters in dis-tributed parameter systems. Finite difference method is used to solve the state equations and sensitivity equations which is derived from the state equations.Newton-Raphson method is used to estimate the unknown par ameters.ldentification criterion is the output least square error. Com-putational resuIts of simulation identification show that this method is simple and direct, conception clear, precision high and having wide scope of applications. |
