摘要
以线性系统频率响应函数的辨识为研究课题 ,对系统辨识中所面临的各种干扰噪声对模型精度估计的影响进行了系统的研究。给出了各种条件下的频响函数的估计 ,为实验辨识频响函数提供了理论依据。
Serving as the question for study with identification of the frequency response function of the linear system,the effects of noises for estimated accuracy are discussed.The estimating formulae of the frequency response function under the various conditions are difined.The formulae can supply the foundations for theory and can be applied in practical engineering problems.
