摘要
阐述了由阶跃响应确定超宽频带与甚宽频带地震计二阶系统传递函数的特征参数的方法。首先分析了 现有的曲线拟合法在测试精度、收敛速度、拟合方法的通用性等方面存在的不足,然后给出了一种更加完善的精确 求取二阶系统传递函数特征参数的方法———加权动态拟合法,详细论述了加权动态拟合法的数学原理,并设计了 拟合计算程序。
This paper discusses a method for determining the characteristic parameters of the 2nd order transfer function by step response. After some insufficiencies in precision, speed, universality of existing curve-fit method havig been analyzed, a better, accurate method—Dynamic Weighted Fit Method is presented. The mathematics principle of Dynamic Weighted Fit Method is discussed in detail and the software of fit computation is designed.
