空间惯性传感器数据驱动自适应非对称约束控制

Data Driven-Based Asymmetric Constrained Control for Space Inertia Sensor

  • 摘要: 在空间引力波探测航天器平台系统控制框架下,针对空间惯性传感器这一关键载荷具备非线性未建模动态且存在性能约束的高精度控制问题,提出一种基于数据驱动理论的数据驱动自适应控制方案,实现空间惯性传感器动力学系统作为一类非仿射非全局Lipstchiz连续系统时的精确稳定控制目标。基于模糊规则建立系统附加不确定性估计器,利用其通用逼近特性保证估计误差的有界性。基于控制障碍函数(Control Barrier Function,BLF)构建非对称性能约束,利用BLF设计的控制器实现闭环信号的非对称约束控制。根据收缩映射原理及离散时间系统Lyapunov理论分析各闭环信号及自适应估计的有界性,数值仿真验证了该数据驱动自适应非对称约束控制方案的可行性和有效性。

     

    Abstract: Under the control framework of space gravitational wave detection spacecraft platform system, aiming at the high-precision control of nonlinear unmodeled dynamics and performance constraints of space inertial sensor, in this paper, a data-based adaptive control scheme based on data-driven theory was proposed to realize accurate and stable control target of non-affine non-global Lipstchiz space inertial sensor dynamic system. Based on the fuzzy rule, an additional uncertainty estimator is established, and its general approximation characteristics are used to ensure the bounded estimation error. Based on the Control Barrier Function (BLF), an asymmetric performance constraint is constructed, and the BLF-based controller is used to realize the asymmetric constraint control of the closed-loop signal. According to the principle of contraction mapping and the Lyapunov theory of discrete-time system, the boundedness of each closed-loop signal and adaptive estimation is analyzed, and numerical simulation verifies the feasibility and effectiveness of the data-driven adaptive asymmetric constraint control scheme.
