Robust controllerdesign withroad adaptation of semi-active suspension system

In this present paper, the road profiles are generated according to the ISO 8606:2016 standard to compare the differential of the road profile when changing the conditions. The semi-active suspension techniques are the solution to this problem and capable of reducing road vibrations effectively. The vertical quarter car model is installed with semi-active suspension system using Electrorheological shock absorber (ER damper) also considered to study the response of the vehicle to the road profile.
