摘要/Abstract

摘要： 卫星激光通信终端控制系统的稳定性是激光通信链路建立与保持过程中的重要性能指标。以终端天线与快速倾斜镜(FSM)两个内回路控制器设计为基础,建立了当电荷耦合(CCD)探测器获得对方终端位置信息构成激光闭合回路时整个激光通信控制系统模型,并根据时滞依赖稳定性定理推导了系统渐近稳定的充分条件,在此基础上对不稳定情况,结合锥补法提出了修正状态反馈设计方案。仿真表明,通过该方案设计得到的控制器,可以保证系统的稳定性,而激光通信控制系统的粗、精回路具有合适的系统带宽,可以协调地工作。

Abstract: The stability of a satellite laser communication terminal control system is a critical performance index in the construction and maintenance of a communication link. Based on the internal loop of the terminal antenna and fast steer mirror (FSM) controllers, a complete control system model is established for the case when the charge coupled device (CCD) detector receives the position of the cooperative terminal to form a closed laser loop. The sufficient condition of system asymptotic stability is induced according to the time delay dependent stability theorem. In order to revise the unstable internal loop design, a state feedback is proposed which combined the sufficient condition and the cone complementary algorithm. The simulation proves that the controller achieved through this scheme is able to keep system stability and provide proper system bandwidth to both coarse and fine loops for their coordination.

Key words: satellite laser communication, terminal control system, system stability, time delay dependent, cone complementary algorithm
