摘要
为测试星载计算机软件和硬件接口实时性能,采用dSPACE多处理器系统设计了卫星姿态和轨道控制实时仿真系统.介绍了该系统硬件和Simulink模型总体结构.采用Simulink、Stateflow和S函数建立了该系统的关键模型——串口通信接口模型.仿真结果表明设计的实时仿真系统和接口模型是有效的.
To test the real-time performance of the software and hardware of on-board computer, a real-time simulation system of satellite' s attitude and orbit control was devised based on dSPACE multiprocessor realtime system. The whole architectures of the hardware and Simulink models of this real-time simulation system were presented. Using Simulink, Stateflow and S-function toolboxes, the key models of the serial-port communication of this system were designed. Simulation results demonstrate the effectiveness of the real-time simulation system and its interface models.
