基于VxWorks的半实物仿真系统的构建

his paper gives the fundamental process of building a hardware-in-the-loop simulation system ,taken the National Instruments Company(NI)PCI-6733 board for example,first,given the board driver design process under VxWorks,after completing the board driver design and debugging, using S-function technology, completed the Simulink driver module development. Finally, for the hardware platform, configurated the code generation compiled files, models are automatically transformed into executable code running on real time operation system VxWorks based on hardware platform. Successfully achieved the correct operation on the target machine. Based on this method implements the simulation system has a modular structure, flexible configuration, easy expansion and upgrades features.
