摘　　要：基于非线性模型 ,研究了卫星编队飞行的控制问题。首先 ,推导了精确的非线性相对运动动力学方程 ;然后 ,设计了带滤波器的无速度测量控制律 ,并使用拉萨尔不变集原理证明闭环系统是全局渐近稳定的 ;最后 。Based on the nonlinear model, the problem of control f or satellite formation flying is investigated. First the exact nonlinear dynamics equations of relative motion is derived. Then the control law without velocity measurement is designed based on a filter and the closed loop system is proven t o be globally asymptotically stable. At last, numerical simulation results are presented to illustrate the theoretical analysis.
