摘要
分布式卫星构形精确保持是实现分布式卫星任务的关键技术。在控制模型不精确和摄动力不确定的条件下,经典控制方法在鲁棒性、动态品质和静态指标的权衡等方面存在不足。本文利用变结构控制方法,设计了分布式卫星精确构形保持的控制器,使控制方法对摄动干扰、模型不确定等具有鲁棒性,因而使构形保持方法在参考轨道存在小偏心率、摄动力存在等非理想情况下仍然可以正常进行。利用高精度动力学仿真环境,对方法的先进性进行了检验。
Formation keeping is a key technology of the distributed satellite system. Traditional control has many disadvantages in robust and control performance in the presence of modeling errors and uncertain perturbations. This paper designs a controller for formation keeping of distributed satellites using the variable structure control method, which has robustness to modeling errors and perturbations, so that the formation configuration can be kept properly for the reference orbit with small eccentricity and perturbations. The control law is then established under a high fidelity simulation environment.
