摘要
为了满足深空天文观测的高质量成像,对空间望远镜的系统稳像精度提出了很高的要求。大口径快摆镜(LAFSM)的控制是实现天文观测中精密稳像系统的关键,其性能决定了空间望远镜的视轴稳定精度。采用内模控制与H∞结合的方式,设计了复合精密稳像控制系统,并对其控制性能进行了分析。仿真结果表明,控制器具有较强的稳定性和鲁棒性。
Abstract
To guarantee high image quality of astronomical observation,high-precision stabilization system is needed for space telescope.The control of Large-Aperture Fast Steering Mirror (LAFSM) is the key for realizing precise image stabilization,whose performance determines the boresight stabilization accuracy of the space telescope.Both Internal Model Control (IMC) and H∞ are employed to design a compound control system, and an analysis is made to its controlling performance.The simulation results show that the controller has strong stability and robustness.
