本文提出了一种激励三维旋转太阳帆膜的控制方法。使用光学属性切换，输入作为太阳辐射压力大小的变化给出。由于其非线性和平衡状态的变化，该系统的共振点随着振动状态的变化而变化。为了解决这个问题，本研究开发了一种自动跟踪谐振点的状态反馈控制律。所提出的方法能够对帆上的执行器进行分散控制，每个执行器仅使用振动状态信息独立地确定控制输入。使用数值模拟验证了所提出的方法。结果表明，非线性系统的行为与线性系统不同，并且无论共振点变化如何，使用分散控制振动都会增加。
The present paper proposes a control method to excite spinning solar sail membranes for three-dimensional use. Using optical property switching, the input is given as the change in magnitude of the solar radiation pressure. The resonance point of this system varies with the vibration state due to its nonlinearity and the change in equilibrium state. To deal with this, a state feedback control law that automatically tracks the resonance point is developed in the present study. The proposed method enables decentralized control of the actuators on the sail, each of which determines the control input independently using only the information of vibration state. The proposed method is validated using numerical simulations. The results show that the nonlinear system behaves differently from the linear system, and the vibration grows using the decentralized control regardless of resonance point variation.
