摘要
为验证微型核原理样机软/硬件实时性能,采用dSPACE实时仿真器建立以微型核为核心的实时仿真验证系统。针对搭建微型核实时仿真验证系统的要求,重点解决了如何用dSPACE仿真器模拟外部实时仿真环境,以及微型核CAN总线和dSPACE仿真器RS232串口之间数据转换的难题。在系统成功建立的基础上,进行了小卫星姿态控制全模式实时仿真,完成了对微型核实时软/硬件性能的测试。仿真结果证明了本仿真验证系统软/硬件结构的正确性。
To verify the performance of the software and hardware of micro core, a real-time simulation system based on micro core is established by using dSPACE simulation system. According to the requirements of building the real-time simulation system, some technical problems are solved, such as how to use dSPACE system to simulate exterior real-time simulation environments and the data transformation between CAN bus of micro core and serial RS232 of dSPACE. Then, after successfully building the real-time simulation system, the full-mode attitude control simulation is performed to test the real-time performance of software and hardware of micro core. The result of the simulation demonstrates the validity of the software and hardware architecture of this real-time simulation system.
