| 中文摘要 |
| 针对带有控制受限的挠性卫星的姿态机动和振动控制问题, 给出了一类仅利用输出信息的变结构控制和
基于智能材料的主动振动控制技术相结合的复合控制方法. 首先给出变结构姿态控制器的设计来完成卫星姿态机动, 并给出一种切换机制以实现挠性卫星快速姿态机动; 其次, 采用分布式压电元件作为作动器, 设计了应变速率反馈补偿器以增加挠性结构的阻尼, 使其振动能够很快衰减. 最后, 将本文提出的方法应用于三轴稳定挠性卫星的姿态机动控制, 仿真结果表明: 在推力器的控制受限条件下, 完成姿态机动的同时, 有效地抑制挠性附件的振动. |
| 英文摘要 |
| A hybrid control scheme is proposed which combines the variable structure control and the intelligent vibration
control. Based on the variable structure control theory, a discontinuous control law is developed with a new type
of sliding surface. The variable structure control law based on a time-varying sliding surface is applied in the exterior
of a small sliding region, while the conventional variable structure control law with a linear sliding surface is activated in the interior of the region. For actively damping the excited elastic vibrations, the strain-rate feedback control is also employed by using piezoelectric materials as additional sensors and actuators. Finally, simulation results show that the
rotational maneuver and the vibration suppression are realized in spite of the presence of disturbance torque and control input constraint. |
