Investigation on Performances of Different types of Classical Controllers in Active Vibration Control

Abstract

For many of the applications a light weight system with higher speed need to be designed. But vibration is a prominent factor in this case. Active vibration control method is an efficient method to eliminate the undesired vibration. This technique finds application in many engineering fields. Vibration control of a smart cantilever beam using this method is presented in this study. Both experimental and simulation techniques are used to study the control of vibration of the beam. Various classical controllers like Proportional, Proportional - Integral, and Proportional -Integral Plus Derivative controllers are used and performances of these controllers are compared. An experimental set up is made for this study and controllers are designed in LabView©platform. A closed loop control system is developed to study active vibration control technique. The experimental result shows effective control of vibration of the beam structure using different classical controllers. In the present study, simulation is also carried out to demonstrate the active vibration control of cantilever beam. ANSYS© and MATLAB© softwares are used for this purpose. Both open loop and closed loop transient responses of the beam are obtained and the results show the effective vibration suppression of the beam. Finally, the experimental and simulation results are compared.
