主 题：solar sail solar radiation pressure vibration mode self-excited oscillation mechanical resonance decentralized control
摘 要：The present paper proposes a control method to excite spinning solar sail membranes for three-dimensional *** optical property switching,the input is given as the change in magnitude of the solar radiation *** resonance point of this system varies with the vibration state due to its nonlinearity and the change in equilibrium *** deal with this,a state feedback control law that automatically tracks the resonance point is developed in the present *** 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 *** proposed method is validated using numerical *** 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.
