摘要: 研究了在控制量受限的情况下,挠性航天器的变结构输出反馈和干扰补偿的控制方法。在控制律的设计中,用变结构输出反馈控制来抑制挠性附件的振动,用扩展状态观测器对系统的不确定性和干扰力矩进行估计并给予实时补偿。仿真结果验证了该方法的有效性。

关键词: 挠性航天器, 变结构控制, 输出反馈, 扩展状态观测器

Abstract:  A variable structure output feedback control method with disturbance compensation is presented under control torque saturation for the flexible spacecraft.In this method,the variable structure output feedback control suppresses the vibration of flexible appendages,the unknown dynamics and disturbing torques are estimated by an extended state observer and are compensated on line.The simulation results show the method is effective.

Key words: flexible spacecraft, variable structure control, output feedback, extended state observer
