Parameter identification of two-time-scale nonlinear transient models
Background Context Material fatigue is one of the key phenomena whose study is essential to design and develop modern industrial parts: many of the classical methods used in the industry, such as those described in Ref. [1], allow to estimate fatigue life through cumulative formulas. However, these latter do not take into account the history associated with the loading, and tend to give poor re...
متن کاملTime-multi-scale parameter identification of models describing material fatigue
! Guillaume Puel1 ! 1Laboratoire MSSMat (Ecole Centrale Paris/CNRS UMR8579), Grande voie des vignes, 92290 Châtenay-Malabry, France ! When dealing with the numerical prediction of material fatigue, classical life estimation methods, such as those described in [1], can give poor results as far as one is interested with complex loading histories (such as a loading with a slow-evolving average) ...
متن کاملA Continuous-time Identification Method for Parameter Estimation of Nonlinear Dynamic Load Models of Power Systems
More accurate dynamic load models get better description of the dynamic load characteristic and its relation to voltage stability. In this paper, a second order Taylor series expansion model is presented as the simplification of the popular used exponential recovery dynamic load model. Then, a frequency weighted least-squares based Hartley modulating functions (HMF) method is developed to estim...
متن کاملA two-time-scale, two-temperature scenario for nonlinear rheology
We investigate a general scenario for "glassy" or "jammed" systems driven by an external, nonconservative force, analogous to a shear force in a fluid. In this scenario, the drive results in the suppression of the usual aging process, and the correlation and response functions become time translation invariant. The relaxation time and the response functions are then dependent on the intensity o...
متن کاملGuaranteed Nonlinear Parameter Estimation for Continuous - Time Dynamical Models
This paper is about parameter estimation for models described by a continuoustime state equation from discrete-time measurements. Guaranteed solutions to this problem are proposed in probabilistic and bounded-error contexts, based on Müller’s theorems and interval analysis. In a probabilistic context where parameter estimation boils down to parameter optimization, this makes it possible to char...
