摘　　要：研究了绳系卫星受到太空碎片冲击时的最优控制响应。考虑系绳弹性和复杂边界约束,利用二阶微分包含及Legendre伪谱算法,提出了三维绳系卫星系统最优控制方法并给出了其回收过程最优控制的响应,获得了太空碎片对绳系卫星的冲击响应规律。The optimal retrievaal control for a three-dimensional tethered satellite system subject to different level of impacts from space debris was presented here.Tether elasticity and complex constraints were taken into consideration in the controller design firstly,which featured full exploitation of a second-order differential inclusion concept and a Legendre pseudo-spectral algorithm.The optimal tension and state profiles were solved with respect to the initial impact velocities.The various effects of impacts from space debris on the tethered satellite system were analyzed.
