General Realization Algorithm for Modal Identification of Linear Dynamic Systems
The general realization algorithm GRA is developed to identify modal parameters of linear multi-degree-of-freedom dynamic systems subjected to measured known arbitrary dynamic loading from known initial conditions. The GRA extends the well known eigensystem realization algorithm ERA based on Hankel matrix decomposition by allowing an arbitrary input signal in the realization algorithm. This gen...
متن کاملAn Algorithm for Multi-Realization of Nonlinear MIMO Systems
This paper presents a theoretical approach to implementation of the “Multi-realization of nonlinear MIMO systems”. This method aims to find state-variable realization for a set of systems, sharing as many parameters as possible. In this paper a special nonlinear multi-realization problem, namely the multi-realization of feedback linearizable nonlinear systems is considered and an algorithm for ...

متن کاملSequential second derivative general linear methods for stiff systems
Second derivative general linear methods (SGLMs) as an extension of general linear methods (GLMs) have been introduced to improve the stability and accuracy properties of GLMs. The coefficients of SGLMs are given by six matrices, instead of four matrices for GLMs, which are obtained by solving nonlinear systems of order and usually Runge--Kutta stability conditions. In this p...
متن کاملAn Evolutionary Algorithm for Linear Systems Identification
This paper presents a systems identification method, for discrete time linear systems, based on an evolutionary approach, which allows achieving the selection of a suitable structure and the parameters estimation, using non conventional objective functions. This algorithm incorporates parametric crossover and parametric mutation along a weighted gradient direction [1]. The performance of the pr...
