| 摘 要： | 有效载荷或星上运动部件相对卫星平台转动引入的扰动力矩严重影响卫星平台的姿态稳定度和指向精度.为满足卫星姿态高稳定度要求,采用正余弦细分驱动原理对帆板驱动机构(SADA)细分,并利用力矩补偿机构补偿有效载荷运动所引入的扰动力矩.此外,针对补偿机构自身存在的摩擦力矩设计补偿控制律,以改善其力矩输出性能.仿真算例表明设计方案有效.

| Abstract: | The movement of the payloads or mobile bodies with respect to the spacecraft platform disturbs the attitude stability and the pointing accuracy of the platform seriously.For satellite's requirement for high stability,the principle of sin-cosine subdivision is adopted to make the SADA micro-step;furthermore,the mechanism is used to compensate the disturbing torques of payloads.For the compensating mechanism system,a controller is designed to compensate the friction torque,so as to improve the output performa... |
