single-step iteration

Dissert on prime identification method of frequency response function, estimation method of coherence function and iteration process, etc. By applying these to single input-single output and multiple input-multiple output system to recur road roughness, the tests achieve preferable results.

详细论述了频率响应函数的主要辨识方法，相干函数的估计方法，迭代过程等，并应用于单输入单输出和多输入多输出系统再现路面不平度的试验，取得了较好的效果。
