摘要
研究了变构型空间站的姿态动力学建模和控制问题 .首先采用拟坐标拉格朗日方法建立了带有挠性附件的固定构型空间站的刚 挠耦合数学模型 ,然后根据空间站构型变化过程的特点 ,并经过适当的变换 ,得到了变构型空间站的刚 挠耦合数学模型 ,最后采用一种新的分散变结构控制算法对空间站的姿态和挠性结构振动进行了一体化控制 。
First, a quasi-coordinate Lagrange method was employed to derive a mathematical model for a space station with a fixed structure containing flexible appendages. Then, taking into account the characteristics of structure change, a mathematical model for a space station with changing structure was generated through some appropriate transformations. On the above basis, a new decentralized variable-structure control algorithm was adopted to control the attitude and the flexible vibrations of the space station. Finally, the validity of the proposed scheme was verified by simulation results.
