以ASTRODI(Astrodynamical Space Test of Relativity using Optical DevicesI,单航天器天文激光动力学)为例介绍无拖曳卫星的结构及其工作原理.推导了其动力学方程,并在此基础上建立了卫星的动力学数值仿真器.将H_2最优控制理论运用于以噪声压制为主要目的的无拖曳卫星控制系统的设计,通过传递函数法及数值法双重分析表明所设计的控制器能符合卫星的控制要求,同时表明在控制器没计过程中采用的线性化假设是适当的.
Taking ASTRODI (Astrodynamical Space Test of Relativity using Optical Devices I) as an example to introduce the structure and working principle of towless satellites, the kinetic equations of the towless satellites are deduced, and the power of the satellites is established The numerical simulator is used to apply H 2 optimal control theory to the design of towless satellite control system with noise suppression as the main objective. The dual analysis of transfer function method and numerical method shows that the designed controller can meet the satellite control requirements, At the same time, it is shown that the linearization assumption used in the controller negligence is appropriate.
