FREQUENCY RESPONSE CHARACTERISTIC OF NONLINEAR POLYNOMIAL SYSTEM
-
摘要: 给出了多项式非线性系统的多维频率响应函数(MFRF)的解析表达式及其主要特性─—极点频率的定义和性质。对工程中多采用的三次多项式系统定义了广义传递函数,可在一维频率域中研究响应的谱结构。Abstract: For nonlinear polynomial system,the analytical formula of the Multi-dimensionalFrequency Response Function(MFRF)are derived and the pole frequeney set is defined inthis paper.For applications in engineering,the extented transfer functionsin one-frequencydomain are defined basing on the investigation on the response frequency spectral structures.
