Estudo de metodologias para identificação dos parâmetros de motores de corrente contínua e imã permanente, e validação experimental do modelo dinâmico através de técnicas de controle moderno

Abstract

This paper proposes a study of two methodologies to identify parameters from the dynamic model of permanent magnet DC motors. The first one consists in the application of adaptive parameters identification techniques and the second one consists in applying trust-region for nonlinear least squares techniques using MATLAB/Simulink tool. This paper also applies two projects of velocity control for evaluation of the models. The first project is about using a mixed control H2/H∞ and the second one is about using poles allocation by complete auto-structure attribution. The error between the results experimentally obtained from the real system and the ones obtained from the simulation will be evaluated through the normalized root mean squared error.
