摘　　要：快速原型仿真是实时仿真的一种,它处于产品研发的算法设计阶段与具体实现阶段之间,是产品研制过程中的一个重要环节。介绍了快速原型技术的发展与优势,搭建了基于DSP的快速原型硬件平台;针对仿真平台,开发了simulink下的底层接口驱动;实现了飞行控制系统的仿真模型在快速原型上的自动代码生成,并完成了半实物仿真。研究表明,通过使用快速原型对算法进行验证,可以方便快捷地将simulink模型应用于半实物仿真系统,降低了算法验证的难度,缩短研制周期,并提高仿真系统的灵活性和可靠性。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.
