Atenuação de vibrações mecânicas em um sistema com 1gdl através da utilização de controladores PID

Abstract

The present work presents a mechanical vibration attenuation in a one degree of freedom system through the active vibration control, more specifically using PID controllers, being the control action performed by electromagnetic actuators. The system was mathematically modeled, which enabled the analysis of the most widespread tuning methods for PID controllers in the literature, due to some factors it was decided by the use of the computational optimization method, using the software Matlab®.To obtain a more refined result some boundary conditions were defined for the system response in order to filter the results based on the desired response wich proved to be adequate for the elaboration of the experimental tests. From the analysis and comparison of the obtained results the methodology was validated, proving the effectiveness of the PID controllers in the attenuation of vibrations in mechanical systems.
