相对空间目标任意位置悬停闭环控制方法研究

研究了相对空间目标任意位置悬停的控制方法,针对现有的开环控制方法对外部干扰和初始误差敏感的问题,基于Hill方程提出了悬停闭环控制方法。进行了仿真计算,证明了方法的有效性。仿真结果表明:该文方法的燃料消耗与开环控制接近而控制性能更好,可以在具有初始速度误差的情况下实现相对于空间目标的任意位置悬停。

Study of Close-loop Hovering Method at Any Selected Position to Space Target

The method of hovering at any selected position to spacecraft target was studied.For the present open-loop method was sensitive to external disturbance and initial error,a close-loop hovering method was proposed based on the Hill equation.The simulation was performed and the method was validated.It shows that the fuel consumption of two control methods are approximate but the performance of the close-loop control is better,which can realize hovering at any selected position to spacecraft target in spite of ...
