2014中国汽车工程学会年会用户论文集：To develop a new kind of damping control system for semi-active air suspension，The structure and working mechanism of one specific type of semi-active air suspension is analyzed. A sky-hook suspension is used as the reference model，and The damping control system of vehicle using semi-active air suspension is proposed by Variable Structure Control (VSC) .The model of The damping control system of vehicle using semi-active air suspension is constructed in Matlab/Simulink. The four-wheel random road surface model has been used as. The input of the simulation model，and the car body vibration is studied. Simulating results show that the riding performance of vehicle is obviously improved by The proposed damping control system.变结构控制方法对阻尼半开关控制器的行为
