念,并实现了仿真程序的重用。-For the three-axis stabilized satellite attitude control system, discrete event simulation platform for OMNeT++ based on the establishment of a star tracker and gyro for the sensor, Reaction Wheel for the implementation of closed-loop control simulation system bodies. Dual-vector attitude determination algorithm and P ID control algorithm, the satellite-to-ground directional mode, the control precision of the simulation. The simulation results clearly reflect the star tracker and reaction flywheel output delay on the control precision effects. Consistent with the simulation system and modular object-oriented programming concepts, and realize the reuse of the simulation program.
