摘要：

In this paper, the performance of a robust control scheme for a Macpherson suspension system is investigated using new dynamic and kinematic models. While the new dynamic model incorporates the kinematics of the suspension in order to have a superior description of the plant dynamics, the three-dimensional kinematic model is used to evaluate the wheel motion subject to controlled force variation. A new definition of the measurement of the wheel-road contact is proposed based on the real function of the control arm. In addition, it is recommended to integrate the vertical displacement of the chassis in the formulation of the control design in order to improve wheel motions. It is shown that the robust semi-active suspension system has superior performance compared with those of a modified skyhook controller system and a passivesystem.
