摘要:

针对存在外部有界干扰和控制饱和的欠驱动直连式三体旋转绳系卫星系统姿态跟踪控制问题,提出了一种分布式非线性控制方法。首先考虑单体欠驱动绳系卫星姿态模型,由于其复杂的非完整动力学特性,应用微分同胚映射的方法先将模型进行转换,进一步基于反步法设计了欠驱动姿态跟踪滑模控制器,并结合抗饱和方法解决了控制受限的问题。然后应用Lyapunov稳定性定理证明了其闭环系统的一致最终有界性。进一步考虑绳系卫星系统的运动同步性,将欠驱动单体绳系卫星姿态控制器设计扩展至直连式三体绳系卫星姿态系统,设计了分布式欠驱动非线性控制器。最后进行了数学仿真,验证了本文所设计控制方法的有效性。

Abstract:

A decentralized nonlinear control strategy is proposed for attitude tracking of underactuated three-inline spinning tethered satellite system in the presence of bounded disturbances and control saturation. For an underactuated single-tethered satellite, a change of coordinates by nonlinear diffeomorphism is used for the complex dynamics of non-complete. Then, a robust sliding mode control scheme is proposed such that the underactuated tethered satellite attitude system is able to track the command signals in the presence of control saturation based on backstepping philosophy combined with anti-windup technique. Within the Lyapunov framework, the uniformly ultimate boundedness of the system states is guaranteed. Further, considering the movement synchronization of tethered satellite system, the attitude controller design for underactuated single-tethered satellite is extended to the three-inline system and a decentralized attitude tracking controller is developed. Numerical simulation results demonstrate the effective of the control strategy.

Key words: tethered satellites, underactuated system, attitude control, robust control, control saturation
