Active Vibration Control of Passenger Seat in Quarter Car Model using Supertwisting Controller

Abstract

The objective of present study is vibartion control of passenger seat in active quarter car model having three degrees of freedom. Passenger ride comfort issues are considered under random road excitation using simulation work in time and frequency domain. The designed supertwisting controller is applied in main suspension of active quarter car model. The proposed controller showed effectiveness in vibration suppression of passenger seat acceleration and displacement responses as compared to passive one. Simulation work in graphical and mathematical results showed the superior performance of the designed supertwisting sliding mode controller.
