摘要:
针对带有输入时延的刚性航天器提出一种姿态稳定性控制方法,首先利用反步法构造李雅普诺夫控制函数,由此得到使系统全局渐近稳定的时延补偿控制器。由于航天器系统为强耦合非线性系统,基于反最优理论,对非线性时延系统构造关于系统状态量和控制力矩的目标函数,该目标函数体现了能耗的重要性,并得到相应的最优控制器。将无优化指标考虑的控制器与最优控制器进行性能比较,非最优控制器所需能量消耗较大,仿真中给出了定量分析结果。仿真结果显示,不同时延情况下,该控制器均可以有效控制航天器姿态稳定,并且对于时延估计偏差具有鲁棒性。
Abstract:
An attitude stabilization controller of the rigid spacecraft in the presence of input delay was pro­posed. Firstly,a Lyapunov function was constructed after backstepping transformation of the original spacecraft model,and a time delay compensated controller that can guarantee global asymptotic stability was obtained. Considering the strong coupling nonlinearity of spacecraft system,the inverse optimal theory was then utilized to construct a cost functional with penalty on both system states and control torque, which reflects the importance of energy cost,and the optimal controller was consequently obtained. Com­pared withi the optimal controller,the controller without optimal consideration costs more energy,quantita­tive analysis was given in simulation.Simulation results show the proposed controller is effective In attitude stabilization with different time delay,moreover,it is robust with delay uncertainty.
