A nonlinear active disturbance rejection attitude controller (ADRAC) with double closed-loop is proposed for the satellite. For comparison purpose, a classic PID controller, which is actually used in certain flexible satellite is considered.

• 提出了一种双闭环自抗扰姿态控制器 (ADRAC) ,并从鲁棒性、干扰抑制、动静态性能指标和振动抑制等方面与使用于某挠性卫星的传统PID控制器进行了比较。
