This paper deals with modeling and control of a semi-active suspension made up with a new industrial semi-active damper, in order to improve comfort and road-holding level of the vehicle. In the past few years, many control strategies have been developed using linear suspension models. A nonlinear model of the industrial damper is developed with physical equations and integrated in a quarter vehicle model. Some tests are done on the real damper in order to validate the model. The comfort and road-holding level of the semi active suspension are studied using some adapted criteria and compared to the passive ones using simulations. These results emphasize the performances improvement resulting from the control of the damper.
