1. System identification and active vibration control of a flexible structure
The aim of this paper is to illustrate the active control of vibration of a flexible structure using a model-based digital controller. The state-space model of the system is derived using a system identification technique known as the Observer/Kalman Filter Identification (OKID) method together with Eigensystem Realization Algorithm (ERA). Based on the measu

2. A Numerical and Experimental Evaluation of ERA and ERA/OKID for Mechanical Systems Identification / Avaliação numérica e experimental dos métodos ERA e ERA/OKID para a identificação de sistemas mecânicos
This work presents two algorithms of identification of state-space linear systems, as follows: ERA (Eigensystem Realization Algorithm), developed by Juang and Pappa (1985), and ERA/ OKID (Observer/ Kalman Filter Identification), by Phan et al. (1992). Both were conceived at the environment of Aerospace Engineering, where it was indispensable the appearance o

4. IDENTIFICACIÓN DE SISTEMAS DE EXTRUCTURAS MECÁNICAS Y APLICACIONES / IDENTIFICATION OF MECHANICAL SYSTEMS WITH APPLICATIONS / IDENTIFICAÇÃO DE SISTEMAS DE ESTRUTURAS MECÂNICAS E APLICAÇÕES
The aims of this work are three: First, to make a brief review of linear system and estimation theory used in mechanical structure problems. Second, to study an algorithm called ERA (Eigensystem Realization Algorithm) that provides a minimal realization using the input (forces, moments, impulses) and output signals (accelerations). Third, to develop some num
