Real-time simulation of satellite attitude control based on low cost embedded system

Considering the limitation of off-line simulation and the high cost of many real-time simulation equipments used in aeronautical and astronautical fields, a low-cost embedded real-time simulation system has been developed for the research of satellite attitude control. By using the mature ARM/DSP chip as the processor and the embedded Linux operating system in the target machine, and the monitoring and management interface based on the graphical programming language LabVIEW in the host computer, this system has successfully addressed key technical issues of real-time simulation. It has optimized the four essential components of the satellite attitude control closed-loop system. Initial application of the system has validated its effectiveness, and therefore proved that it will be significant in the engineering applications.
