Atenuação de vibrações utilizando modelos linearizados de atuadores eletromagnéticos

Abstract

In the present work, it is developed a computational approach regarding active vibration control techniques applied to flexible rotors using linearized electromagnetic actuators models, techniques such as Quadratic Linear Regulator, Quadratic Linear Regulator solved via linear matrix inequalities and control using linear matrix inequalities with insertion of polytopic uncertainties. Several tests are performed, among them the run-up test, permanent regime and impulse response, to better understand the behavior of each of the techniques analyzed. In addition to the computational analysis, it is proposed the design and start of the construction of a bench of tests aiming the continuity of the research and the experimental validation in future works, a method is also proposed, based on genetic algorithms, to estimate physical quantities of damping and bearing rigidity from the frequency response function obtained from the model.
