SOME ASPECTS ON NONLINEAR SYSTEM IDENTIFICATION

Some Aspects on Nonlinear System Iden- tification

Identi cation of nonlinear systems is a very extensive problem, with roots and branches in several diverse elds. It is not possible to survey the area in a short text. The current presentation gives a subjective view on some essential features in the area. These concern a classi cation of methods, the use of di erent shades of grey in models, and some overall issues like bias-variance trade-o s...

Some Aspects on Nonlinear Black - Box Modeling in System Identi

Some aspects of industrial system identification

The most important and time consuming part of an industrial application of control is the modelling. It may take 50 per cent or more of the entire project. Therefore a major challenge for a control systems supplier like ABB is to constantly try to decrease the engineering effort for modelling. This paper discusses some different aspects of modelling and identification originating from applicati...

global results on some nonlinear partial differential equations for direct and inverse problems

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...

Some Aspects of Nonlinear Lattice Models

A theoretical study of various static and dynamic solutions in a one-dimensional lattice with anharmonic electron-ion coupling is presented. The stability of the different comnensurate groundstates is investigated and both kinkand phonon-excitations are described. The coupling of nonlinear excitations to phonons is discussed in detail. It was pointed out some time ago, that the microscopic orig...
