【摘要】 针对挠性卫星的振动控制问题，提出了一种在姿态机动过程中抑制振动的控制策略。首先建立了考虑干扰载荷的挠性卫星姿态动力学模型，分析了不同形式的干扰载荷对振动模态的影响。为控制姿态机动和干扰载荷引发的振动，提出了预设模态振动控制方法，根据预设被控模态调整动力学模型，在此基础上优化作动器和传感器位置并进行控制器设计。最终通过数值模拟阐述了预设模态振动控制方法的有效性和优势。与现有的振动控制方法相比，该方法选用适当的被控模态和最优作动器/传感器位置，从而大幅提升了振动抑制效果。更多还原

【Abstract】 To address the vibration control issue of flexible satellites, a control strategy aimed at suppressing vibrations during attitude maneuvers is proposed. Initially, an attitude dynamics model of flexible satellites that takes disturbance loads into account is established, and the influences of various forms of disturbance loads on vibration modes are analyzed. To control vibrations induced by both attitude maneuvers and disturbance loads, a prescribed modal vibration control method is put forward. The dynamics model is adjusted based on the preset controlled modes, upon which the positioning optimization of actuators and sensors is conducted, and the controller design is carried out. Ultimately, the effectiveness and advantages of the prescribed modal vibration control method are elucidated through numerical simulations. In comparison with existing vibration control methods, this method selects appropriate controlled modes and optimal actuator/sensor configurations, thereby significantly enhancing the vibration suppression effect.更多还原
