| Abstract: | Based on the dSPACE multiprocessor systems, a real time simulation system of certain flexible satellite's Attitude and Orbit Control System ( AOCS ) is designed for on-board computer-in-the-loop simulation. This paper introduces the software and hardware architecture of this real time simulation system and focuses on the key to simulation of RS 232/422 serial communication between on-board computer and attitude sensors using dSPACE DS 4201s serial port hardware boards.Simulink models for RS 232/422 serial communication of this real time system are designed based on Simulink, Stateflow and S-function toolboxes. The real time simulation of satellite's attitude and orbit control in autonomous mode is completed on the dSPACE systems. Results of simulation show the effectiveness of this real time simulation system and the design of Simulink models for serial communication. |
