针对编队卫星姿态协同跟踪控制中存在相异星间通信时变时间延迟的问题,提出了采用一阶滤波器来设计含通信时延的输出反馈控制器,并通过引入参数在线自适应辨识技术,以实现利用卫星姿态误差信息来实现对卫星的转动惯量进行在线估计.对于系统稳定性的分析,通过构造一新型Lyapunov函数,证明该控制器不仅能够有效地克服通信时间延迟对编队系统协同性的影响,同时可论证无需角速度信息反馈的闭环系统的有界稳定性.最后,将提出的算法应用于只需要角速度信息反馈的卫星编队飞行的协同控制,仿真结果表明该方法的可行性与有效性,具有实际的应用前景.
Aiming at the problem of time-varying time-varying of different intersatellite communication in coordinated tracking control of formation attitude, a first-order filter is proposed to design an output feedback controller with communication delay. By introducing parameter on-line adaptive identification technology, So as to realize the on-line estimation of the satellite’s moment of inertia by using satellite attitude error information.For the analysis of system stability, by constructing a new type of Lyapunov function, it is proved that the controller not only can effectively overcome the communication time delay to the cooperation of formation system The stability of the closed-loop system without angular velocity information feedback can be demonstrated.Finally, the proposed algorithm is applied to the coordinated control of satellite formation flight which only needs feedback of angular velocity information.The simulation results show the feasibility and effectiveness of the proposed method , With practical application prospects.
