| 摘 要： | 本文通过斜坡响应不变法实现离荼到连续传递函数间的转换，运用Ｍａｒｑｕａｒｄｔ阻尼最小二乘法辨识驾驶员ＰＯ预瞄模型的物理参数。辨识结果中，当信噪比为２０ｄＢ、４ｄＢ时，最大偏差分别为１．６％及１０％，从而表明斜坡响应不变法具有很高的辨识精度，且因采用阻尼最小二乘法致使物理参数识精度进一步提高。

| Abstract: | In this paper, a technique to identify physical parameters of PO model is studied using the invariant ramp response method to convert the ARMA to continuous transfer function, and adopting the Marquardt' s damping least square algorithm to solve a set of non linear equations for the physical parameters. According to the results, when SNR is 20dB and 4dB, the maximum deviation is less than 1.6% and 10% respectively. So it was shown that the conversion is of high accuracy, and the Marquardt's algorithm can further improve identification quality. |
