Abstract
In this paper, the 1/4 vehicle model have been simulated. The vehicle body acceleration using optimal
control has been optimized. The vehicle ride comfort is achieved by using robust control, and it has been
compared with optimal control. The active suspension can help the vehicle to have a good dynamic
behavioral. In this paper, two degrees of freedom dynamic vibration model of a general vehicle is
developed through the designation of a closed-loop and robust control system. Irregular road input is
simulated as sinusoidal signals, and the vehicle vibration response is optimized. Using robust control the
vehicle ride comfort has been improved, and using optimal control not only the ride comfort has been
achieved, also the vehicle acceleration is optimized.
