Aiming at the semi-physical simulation of micro-satellite attitude control system using reaction flywheel as actuator, the comprehensive problem of simulation object is lacked. The multi-single-axis air-floating turntable based on nRF24E01 wireless RS232 serial communication module is studied. Matlab XPC Real-time simulation technology, on-board computer and reaction flywheel and optical fiber gyroscope physics in-kind satellite attitude control system three-axis air flotation platform semi-physical simulation program design; the use of the simulation system to the reactionary flywheel as the main actuator of the satellite bias momentum three Axis steady-state control mode was verified by semi-physical simulation. The simulation results show that the performance of the semi-physical simulation platform is good, and the simulation process of the triaxial steady state control example of the bias momentum can be realized. The linkage operation effect of the three-axis sensor and the actuator is observed and the semi-physical simulation system scheme is verified Design is reasonable and reliable.
