Classical PID Controller for Semi-active Vibration Control of Seismically Excited Structure Using Magneto-Rheological Damper

Abstract

In this paper, a Proportional Integral Derivative (PID) controller is designed to mitigate the vibration response of the structure. The simulation is done for three degrees of freedom system under different earthquakes using MATLAB and Simulink. Different earthquakes are considered to find the capability of the controller used. The controller is designed using tuning rules of Zeigler–Nichols ultimate gain method. The controller proposed will reduce the vibrations of the structure as compared to the vibrations obtained without controller. The controller output is given to Magneto-rheological (MR) damper which gives necessary force output, which will be applied to the structure to damp out its vibrations.
