Vibration control of mechanical suspension system using LabVIEW

摘要

The paper presents the practical implementation of feedback control strategy to a laboratory scaled vibration isolator platform. The research was carried out to investigate the performance of vibration suppression capability of feedback controller. Two types of controller schemes were examined and compared involving the classic proportional-integral-derivative (PID) controller and fuzzy logic controller (FLC). The laboratory scaled test rig has been developed using the LabVIEW simulation, which is interfaced with a suitable data acquisition card (NI USB 6008) via a personal computer as the main controller. Appropriate vibration source was applied to the proposed systems to test for the system robustness. Results obtained in this study demonstrated the potential and superiority of the FLC scheme as a robust vibration suppressor compared to the other scheme considered in the study.
