A control algorithm, the Mission-Function Control, is introduced in order to deal successfully with the Problem inherent in dynamics and control of the large flexible space structures(LFSS). Dynamics of the LFSS is most precisely described by the distributed parameter system combined with the concentrated sensors/actuators. Often noted are such difficulty for implementation of control algorithms on LFSS as spillover effect since of too sophisticated application of the existing control algorithms to the LFSS model described by the usual modal expansion method. The Mission-Function Control algorithm is the Liapunov method and derived through inspection of such dynamical feature of the LFSS as the nonlinear and distributed parameter system. The algorithm is successfully applied to 1) control of deployment and retrieval of a subsatellite connected to a main body through a tether, and 2) slew maneuver to slew a space structure for a large angle of attitude with least suppression on the flexural vibration of the flexible structures. The Mission-Function algorithm is also experimentally demonstrated and verified its validity on a slew maneuver of a flexible space structure model. Results of the numerical and experimental analysis confirm preferable features of the Mission-Function control algorithm applied to control of the LFSS and assure the excellent performance of the Mission-Function control.

为了成功地解决大型柔性空间结构（LFSS）的动力学和控制固有的问题，引入了一种控制算法——任务功能控制。 LFSS 的动力学可以通过分布式参数系统与集中传感器/执行器相结合来最精确地描述。人们经常注意到，在 LFSS 上实施控制算法存在溢出效应等困难，因为现有控制算法在通常的模态展开方法描述的 LFSS 模型中的应用过于复杂。任务功能控制算法是李亚普诺夫方法，是通过考察LFSS的非线性、分布参数系统等动力学特性而推导出来的。该算法成功应用于 1）通过系绳连接到主体的子卫星的部署和回收控制，以及 2）回转机动以将空间结构回转到大角度姿态，同时对空间结构的弯曲振动抑制最小灵活的结构。任务功能算法还在柔性空间结构模型的回转机动中进行了实验论证并验证了其有效性。数值和实验分析的结果证实了应用于 LFSS 控制的任务功能控制算法的优选特征，并确保了任务功能控制的优异性能。
