说明：   考虑幅值谱与相位谱的人造地震动模拟与反应谱拟合 我国对《建筑结构抗震规范》进行了修订，将设计反应谱周期由原来的3秒延长到现在的6秒。反应谱周期的延长。 本程序以新规范反应谱作为目标谱，采用三角级数迭加来模拟地震动加速度。(consider amplitude spectrum and phase spectrum of the artificial seismic simulation and pattern fitting response to China's "structural seismic code" the amendment to the design spectrum cycle from three seconds to extend the current six seconds. Response spectrum cycle extension. The new procedures to regulate spectrum as the target spectrum, the use of triangular series superposition to simulate vibration.)

该算法用于自回归输入模型，是一种迭代的算法。其基本思想是基于对数据先进行一次滤波处理，后利用普通最小二乘法对滤波后的数据进行辨识，进而获得无偏一致估计。但是当过程的输出信噪比比较大或模型参数较多时，这种数据白色化处理的可靠性就会下降，辨识结果往往会是有偏估计。数据要充分多，否则辨识精度下降。模型阶次不宜过高。初始值对辨识结果有较大影响。(The algorithm used for autoregressive input model, it is a kind of iterative algorithm. The basic idea is based on data to conduct a filtering processing, after using ordinary least square method to identify the data filter, and then obtain unbiased consensus estimates. But when the process output signal-to-noise ratio is larger or model parameters are too, this kind of data white processs reliability will drop, identification results tend to be biased estimate. Data should fully, otherwise the identification accuracy down. Model order time shoulds not be too high. Initial value to identification results have great influence on.)
