摘要:

研究了具有模型不确定性的多体航天器大角度机动控制问题。航天器姿态动力学方程具有不确定性和非线性。首先通过逆系统方法求得近似伪线性系统,然后应用H混合灵敏度方法和μ综合方法设计了两种鲁棒控制器。通过引入PD控制器,避免了H控制器设计时方程出现奇异。针对航天器中心体与天线同时跟踪不同目标的任务,进行了数值仿真。仿真结果表明在同等条件下两种鲁棒控制器都能满足鲁棒稳定性指标,其中μ控制器的鲁棒性能更好。

Abstract: This paper investigates the robust control of large angle maneuver for the multi-body spacecraft with model uncertaintiesA nonlinear dynamics model with uncertainties is consideredAn approximate pseudo-linear system is developed by using the inverse system methodand two linear robust controllers are designed through the mixed sensitivity Hoptimization and the p synthesis methodrespectivelyA PD controller is used to eliminate the singularity during the mixed sensitivity HoptimizationNumerical examples of the central body and antenna tracking different targets are givenThe simulation results demonstrate that both controllers are robust stableand the robust performance of the μ controller is better than that of the H∞  controller
