报告内容：The analysis and design of nonlinear systems in the frequency domain are challenging topics in the literature. Usually, the harmonic balance method or absolute stability theory etc can be employed. However, limitations might often be encountered due to computational complexity or implicit relationship between system output response and model parameters. Based on the Volterra series theory, a systematic frequency domain analysis and design method referred to as output frequency response function (OFRF) or nonlinear characteristic output spectrum (nCOS) function is developed with a unique parametric characteristic approach in recent years, which demonstrates advantages over its counterparts, bringing obviously unique features, benefits or insights into the understanding of nonlinear influence in the frequency domain. Applications in vibration control, signal processing, fault detection and others are extensively studied in the literature as well. This talk presents a brief introduction to this topic.
