本文在一些新近发展的结果的基础上讨论了非线性系统的频域分析。针对非线性沃尔泰拉系统，提出了一种根据系统时域模型参数分析和设计系统输出频率响应的新方法。给出了基于输出频率响应函数（OFRF）分析的一般方法，讨论了OFRF分析的潜在应用，建立了一些有用的结果和技术，特别是对于任何特定模型参数的非线性系统的分析。这些结果促进和说明了新方法的实际应用。一个机械系统分析的案例研究，以说明这种新的方法。
This paper deals with the frequency domain analysis of nonlinear systems based on some recently developed results. A new systematic approach to the analysis and design of system output frequency response in terms of system time domain model parameters is proposed for nonlinear Volterra systems. A general procedure to conduct an output frequency response function (OFRF)-based analysis is given, the potential applications of the OFRF-based analysis are discussed, and some useful results and techniques are established, especially for the analysis of nonlinear systems with respect to any specific model parameters. These results facilitate and illustrate the practical application of the new method. A case study for the analysis of a mechanical system is provided to illustrate this new method.
