| Abstract: | A vibration control analysis is conducted on a quarter model for the semi-active suspension of a car with magnetorheological (MR) damper. Taking the advantage of iterative linear matrix inequality (ILMI) algorithm in solving output feedback control issues, a static output feedback control method based on ILMI algorithm is proposed for semi-active suspension and a simulation is performed. The results show that with a proper control algorithm, the semi-active suspension with MR damper can effectively improve the ride comfort of vehicles. |
