This paper presents vibration control responses of a commercial vehicle installed with electro-rheological (ER) primary suspensions and a magneto-rheological (MR) seat damper. After formulating the governing equation of motion of the full-vehicle system associated ER and MR dampers, the sky-hook controllers are designed by imposing semi-active actuating conditions. The control algorithms are then implemented via the hardware-in-the-loop simulation, and control responses of vertical displacement and acceleration at the driver’s seat are evaluated under two road conditions; bump and random road.
