Otimização de parâmetros aplicados no controle de vibrações de rotores flexíveis

Abstract

This study consists in the study of the active vibration control of flexible rotors in a computing environment, looking for a mitigating vibration and stability of the structure, for this, the rotor shaft was modeled using the finite element method. Subsequently, the study was based on optimization parameters used in the active control, which was proposed to find an optimum configuration of the control system, resulting in a good compromise between system control power and attenuation of the rotor vibration level, in this case, as it was required more than one goal in the optimization process, a commitment function was used. In terms of optimization techniques we used the heuristic method of Differential Evolution.
