摘要
本文提出利用经典过程辨识法中的相关分析法,求取时域离散数学模型的频率特性。通过实例验证了此方法的有效性。此法误差小,能满足研究和设计上的要求。它适用于线性系统,也适用于非线性系统。
This paper proposes to apply the correlation analisis approach to identify frequency responses
of mathematical models in discrete time domain. A example is given in order to demonstrate the efficien-
cy of the appoch. The calculation results have shown that identification accuracy of the method is very
high and so satisfactory. The method can be used both in linear and in nonlinear systems.
