摘　　要：对大型挠性空间结构多体系统进行了研究,建立了含有阻尼、分布式陀螺部件和约束阻尼的多体挠性空间结构系统主动控制动力学模型;利用算子半群理论,在无穷维函数空间中研究了上述系统的基本特征问题,包括可控性、可观性和稳定性。To study the multi-body system with large flexible space structure, the active control dynamical system model with multi-body flexible space structure is established which has damping, distributed gyroscopic part and constrained damping. By means of theory of semigroups of linear operators, the basic feature of the system is investigated in infinite dimensional functional space, including controllability, observability and stability.
