Abstract: The satellite attitude dynamics equations considering satellite payload were set up for a new generation of earth resource satellite.The satellite attitude was controlled by using genetic algorithm PID self-tuning method.The method effectively elminated the influence of rotatable payloads on satellite attitude.Simulation results show that the control performance of the satellite attitude system is improved,and the difficulties of traditional PID parameter regulation can be avoided by this method.
