Abstract
The present work proposes the active vibration control in a beam of composite material using electromagnetic actuators. The advantage of the use of electromagnetic actuators is the application of the control force without the mechanical contact. The control technique used is the optimal control, specifically the linear quadratic regulator solved by linear matrix inequalities. The system identification is done using the Eigensysten Realization Algorithm/Observer/Kalman Identification, also known as ERA/OKID, where it is a method used to identify modal parameters in complex structures. From the model obtained, the optimum controller is designed, which is responsible for determining the control effort, and the electromagnetic actuators are responsible for applying the control forces to stabilize the system. From this point on, the responses of the numerical simulation and the experimental responses of the system were obtained, in which the vibration attenuation of the system was obtained in both procedures, evaluated through displacement responses and frequency response functions, thus validating the methodology studied.
