对基于控制叶片的太阳帆航天器,推导考虑弹性振动的太阳帆姿态动力学方程和振动方程,利用非约束模态的概念给出了太阳帆航天器动力学方程的求解方法.结合超地球同步转移轨道太阳帆航天器偏航轴对地定向问题,设计了太阳帆俯仰轴的考虑Bang-Bang控制策略的PD控制器,数值仿真结果表明,所设计的基于控制叶片的控制器可以较快、较精确地实现偏航轴对地定向任务.
Based on the controlled blade solar sail spacecraft, the attitude and vibration equations of the solar sail considering the elastic vibration are deduced, and the solution of the solar sail spacecraft dynamics equation is given by using the concept of unconstrained mode. The PD controller considering the Bang-Bang control strategy of the pitch axis of the solar sail is designed, and the numerical simulation results show that the designed controller based on the control blade can be faster, More accurate to achieve yaw axis orientation to the ground task.
