雷达卫星鲁棒逆最优自适应姿态跟踪控制
Tracking cotrol of robust inverse optimal adaptive attitude in radar satellites
摘要
Abstract
A novel method of MRP based robust inverse optimal adaptive tracking controllers was proposed for spacecraft tracking control problem with external disturbances and an uncertain parameters. A robust inverse optimal controller was designed with respect to the designed robust cost function through constructing Lyapunov function and using backstepping method, which avoided solving the Hamilton-Jacobi-Isaacs partial differential equation directly. Input-to-state stability and robustness with respect to external disturbances was achieved through a smaller disturbance attenuation level. An adaptive update law was constructed with respect to adaptive parameters to address the adverse effect of parameters uncertainty. Numerical simulations have demonstrated that the proposed method could not only guarantee the track accuri~cy and improve the robustness but also suppress the adverse effect of both uncertain parameters and unknown disturbance.关键词
