As one of the real--time simulation methods, rapid control prototyping is between the phases of algorithm design and achievement, is a crucial tache in the research and design process for product. In this paper the development and advantage of rapid control prototyping are introduced, the hardware platform based on DSP is constructed. According to the simulation platform, the bottom interface driver under simullnk is developed, the automatic code generation of the control system simulation model in the rapid control prototyping is realized, and the hardware--in--the--loop experiment is completed. The research shows that based on the rapid control prototyping the simulink model can be applied to the hardware--in--the--loop simulation system conveniently and rapidly. The simulation results illustrates that the difficulty of establishing the system is reduced, the development period is shorten, the flexibility and reliability of the simulation system are enhanced.
