Abstract
This paper is related to passenger ride comfort improvement using an active quarter car system. The selected control strategies include PID based super twisting control (PID-STC) and PID based variable gain super twisting control (PID-VGSTC) for reducing the passenger body vibration response. ISO 8608: 2016 standard is used for random road profile generation while ISO 2631-1 standard guidelines are used for ride comfort comparison. The ride comfort performance of passenger body is evaluated and compared using simulation results taking acceleration and displacement response. The ride comfort improvement results shown by active suspension with PID-VGSTC controller were highest compared to other control strategies.
