Active Suspension vibration control using Linear H-Infinity and optimal control

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.
