　　This study discusses the rapid control prototyping approach used for development and investigation of control algorithm in magneto-rheological (MR) semi-active suspension system.Firstly,a multibody dynamic model based on MR suspension system is developed with the aid of VEDYNA software.Based on the model,a new intelligent control algorithm,human simulated intelligent control (HSIC) is proposed and designed.Finally,by means of dSPACE groupware system,the semi-active control prototype of real car has been built up,road test of real car and parameters of online adjustment have also been carried out.The results of offline simulation and real time control show that HSIC can achieve better comfort under assuring stability.They also show that rapid control prototyping (RCP) on the basis of Matlab/Simulink and dSPACE can shorten the research period of vehicle semi-active controller and reduce the cost of research.It is very significant to promote the industrialization of vehicle semi-active controller.
