对失控翻滚目标逼近的增广比例导引律控制

针对失控翻滚目标逼近控制问题进行了研究,设计了增广比例导引律控制器。首先在追踪器视线旋转坐标系上建立了追踪器与逼近点的三维相对运动方程,分析了失控翻滚目标的姿态运动特性,在传统真比例导引律基础上引入对逼近点视线方向的控制,采用基于反馈线性化的增广比例导引律对追踪器进行控制。通过数值仿真验证了所设计的增广比例导引律的正确性和良好的控制性能。

Augmented proportional navigation control for approach to uncontrolled tumbling satellite#br#

The problem of control for approach to uncontrolled tumbling satellites is researched, and an augmented proportional navigation controller is designed. Firstly, a three-dimensional relative motion equation of chaser and approximation points is established on the rotating coordinate system of the line of sight of the chaser. The attitude motion characteristics of the uncontrolled tumbling satellite are analyzed. The control of the line of sight of approximation points is introduced on the basis of the traditional true proportional navigation. The chaser is controlled by augmented proportional navigation based on feedback linearization. The correctness and good control performance of the designed augmented proportional navigation are verified by numerical simulation.
