Abstract：Half-vehicle dynamic models of Active suspension were built on the basis of theory of system dynamics. and separation research method was adopted to independent control to vertical movement of quarter-vehicle models and pitch movement of half-vehicle models; And it was superimposed on the integral control of half-vehicle models. Second The corresponding controller model and simulation model were built through Matlab/Simulink;finally,the Band-Limited White Noise was adopted as the road input to carry out the dynamic performance simulation. The suspension characteristic of active suspension and passive suspension were compared. The result indicated that active suspension's performance was improved obviously, compared with performance of passive suspension.
