This paper aims to use HÂâ€¡ and mixed H2/HÂâ€¡ techniques with a semi active suspension system to increase the passenger's ride comfort performance. A two degree of freedom dynamic model of a vehicle semi-active suspension system was presented. The role of HÂâ€¡ is used to minimize the disturbance effect on the system output whereas H2 is used to improve the transients against random disturbances. The capability of the system of improving comfort of operators has been evaluated through simulations carried out with a validated model of the entire vehicle. The results of this study revealed that the use of mixed H2/HÂâ€¡ with pole placement for a semi-active suspension system showed a great improvement compared with HÂâ€¡ systems. In addition, the results of the simulation showed that ride comfortable of the vehicle can be improved effectively by using the semi-active suspension with mixed H2/HÂâ€¡ control method, and also the mixed H2/HÂâ€¡ control method more effective than the HÂâ€¡ control method. Finally, this paper showed a robust use of both HÂâ€¡ and mixed H2/HÂâ€¡ problem which can be solved using linear matrix inequality (LMI) techniques.
