Genetic Algorithm PID Self-tuning based on the Satellite Attitude Control

文章针对新一代资源卫星建立了带有有效载荷的卫星姿态动力学方程,并且使用遗传算法PID参数自整定的方法进行了卫星姿态控制,有效地消除了可转动载荷对卫星姿态的影响。仿真结果表明,使用遗传算法PID参数自整定方法,对卫星的姿态系统具有较好的控制性能,并且克服了传统PID调参困难的缺点。

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