摘要
研究了交会对接后组合体航天器构型变化带来的姿态控制问题,对执行机构在控制量受限时的控制能力进行了分析,应用基于特征模型的智能自适应控制方法,设计了能适用于不同构型的姿态控制器,分别对组合体在直线构型和L构型对接情况下进行了数学仿真,仿真结果验证了智能自适应控制方法可行并且具有一定的优越性。
The attitude control problem of the assembled spacecraft in rendezvous and docking tasks is studied in this paper. Control capability of thrusters whose outputs are limited is analyzed firstly. Then a controller is designed by using the intelligent adaptive control method based on the characteristic model. The same controller is applied to the one-shaped and L-shaped assembled spacecraft, respectively, and the simulation results are given. In contrast with the robust controller, this method is feasible and of many advantages.
