Dynamics/Control of Large Space Structures plus alpha (Wave absorbing control and Liapunov function control plus alpha)

人们普遍认为，大空间结构的动力学是用分布参数系统描述得最好的，如果在大空间结构的数学描述过程中不进行离散化处理，那么大空间结构的控制器设计得最自然、最合适。研究了LSS控制的一些最新控制方法，并介绍了两种主要基于作者工作的控制器设计方法，即吸波控制和李雅普诺夫函数控制，这些方法既不牺牲离散化，也不存在任何重要的截断效应。对这些方法的基本技术进行了深入的研究，特别是对以LSS模型为原型模型，然后采用三维桁架结构的控制方法进行了实验验证。进一步的扩展和建议将遵循这些研究，包括在第一次弯曲振动中为柔性空间结构模型实现吸波控制器的成功实验验证。本文从分布参数系统的角度对LSS的动力学和控制进行了综述。

It is well recognized that dynamics of large space structures (LSS) are most well described by the distributed parameter system and controllers for LSS is naturally and most appropriately designed if no discretization is adopted in the course of the mathematical description of LSS.Some recent control methods for control of LSS are studied and two approaches based mainly on the works of the author are introduced for the controller design without any sacrifice of discretization and, thus, without any crucial truncation effects including the wave-absorbing control, and the Lyapunov-function control. The fundamental technology of these method is studied thoroughly especially on the aspect of experimental verification of the control methods employing model of LSS,as a prototype model followed by three dimensional truss structures. Further extensions and recommendations will follow these studies including successful experimental verifications on implementation of wave-absorbing controller for a model of flexible space stuctures in the first bending vibrations. These results are summed up in a report as a review of dynamics and control of LSS from the point of distributed parameter system.
