讨论了充液航天器大角度姿态机动自适应非线性动态逆控制设计.推导了航天器-液体晃动耦合系统动力学方程.采用单摆等效力学模型对液体燃料晃动进行动力学建模.由于充液航天器控制系统的强耦合非线性,故采用神经网络构造系统的自适应非线性动态逆控制器.通过实际算例对该控制器的跟综性能进行了测试,结果证明该自适应非线性动态逆控制器在包含液体晃动的情况下仍具有很好的跟综性能.
The design of dynamic adaptive nonlinear dynamic response control of liquid-filled spacecraft with large-angle attitude is discussed. The dynamics equations of the spacecraft-liquid sloshing system are derived. The dynamics of liquid fuel sloshing is modeled by the equivalent pendulum mechanics model. Liquid-filled spacecraft control system of strong coupling nonlinearity, so the use of neural network to construct the system of adaptive nonlinear dynamic inverse controller.Through the actual example of the controller heuristic performance, the results show that the adaptive non-adaptive The linear dynamic inverse controller still has good hedging performance with liquid sloshing.
