Higher-order sinusoidal input describing functions for the analysis of non-linear systems with harmonic responses
TLDR
In this paper, an extension to higher-order describing functions is realized by introducing the concept of the harmonics generator, which relates the magnitude and phase of the higher harmonics of the periodic response of the system to the magnitude of a sinusoidal excitation.About:

Notice of Retraction Harmonic response analysis for beam's vibration under aperiodic excitations
TL;DR: In this paper, a numerical analysis of fine discretization was used to investigate the response of beam under aperiodic excitations, and harmonic response analysis was applied in the solution of a periodic steady response.

TL;DR: In this paper, the response of the plasma to a vertical perturbation, and thus the vertical control, is suspected to be more non-linear than for conventional R/a tokamaks.

Nonlinear frequency response based adaptive vibration controller design for a class of nonlinear systems
Suresh Thenozhi,Yu Tang +1 more
TL;DR: In this article, a nonlinear frequency response function (FRF) based adaptive vibration controller design for a mechanical system with cubic damping nonlinearity and a satellite system is presented. But unlike the previous work, this work does not consider the convergence property of nonlinear systems.

Tuning of ‘Constant in Gain Lead in Phase (CgLp)’ Reset Controller using Higher-orDer Sinusoidal Input Describing Function (HOSIDF)
TL;DR: A recently developed method, which gives deeper insight into the frequency behaviour of non-linear controllers compared to sinusoidal input describing function (DF), is used to obtain a straight-forward tuning method for CgLp compensators.

Multiple-Input Describing Functions and Nonlinear System Design
TL;DR: The theory of automatic control has been advanced in important ways during recent years, particularly with respect to stability and optimal control, but these theories do not, however, lay to rest all questions of importance to the control engineer.

An iterative method for the identification of nonlinear systems using a Hammerstein model
Kumpati S. Narendra,P. Gallman +1 more
TL;DR: In this article, an iterative method is proposed for the identification of nonlinear systems from samples of inputs and outputs in the presence of noise, which consists of a no-memory gain (of an assumed polynomial form) followed by a linear discrete system.
