| 摘 要： | 受步进电机驱动作用，太阳帆板对日定向时卫星姿态受到影响。本文针对帆板驱动不平稳引起的同卫星姿态耦合干扰，提出了一种卫星姿态稳定和太阳帆板对日定向的复合控制方法。卫星姿态稳定采用自抗扰控制器，以估计补偿由帆板驱动和系统不确定性引起的干扰，并在此基础上，设计了步进电机自适应电流补偿驱动器，以克服帆板驱动机构摩擦力矩和谐波力矩影响。仿真结果表明，该方法能大大提高卫星姿态控制精度和稳定度，同时还改善了帆板对日定向的精度。

| Abstract: | The attitude of satellite is disturbed under the influence of step motor driving during the period of solar array pointing to the sun.Considering the coupling disturbances with satellite attitude caused by driving fluctuation,a compound controller is designed for satellite attitude stabilization and solar array pointing to the sun.For the rigid body attitude stabilization,an Active Disturbance Rejection Controller(ADRC)is proposed to estimate and compensate the disturbances induced by solar array driving an... |
