| 摘 要： | 主要研究了针对非合作航天器的自主交会和拦截两种接近模式的控制律。根据非线性相对运动方程,采用李雅普诺夫(Lyapunov)方法设计了自主交会的控制律;并对该控制律进行了改进,使其适用于拦截模式,能以一定的相对速度接近目标。同时针对非合作目标存在机动的情况,采用Lyapunov最小-最大方法设计了自主接近的控制律。仿真结果证明了基于Lyapunov方法的自主接近控制律的有效性。

| Abstract: | Two control laws for autonomous rendezvous and interception with non-cooperative target were designed using Lyapunov approach.First a control law for autonomous rendezvous was derived according to the nonlinear relative motion dynamics.Then the control law was improved in order to apply to the interception mode,which could ensure the chaser approaches the target at a certain relative velocity.Meanwhile considering the maneuver of the non-cooperative target,a new control law for autonomous proximity was derived using Lyapunov min-max approach.The simulation results validate the availability of control laws for autonomous proximity based on Lyapunov approach. |
