| 摘 要： | 当将万向节的相对转动角速度作为航天器系统姿态运动规划的控制输入变量时,由于航天器系统的控制输入的数目少于系统的自由度数目,系统的姿态运动成为典型的欠驱动非完整系统的运动规划问题,其运动控制问题变得非常复杂。提出了一种应用粒子群算法优化系统姿态运动规划的数值算法。数值仿真结果表明了该方法的有效性。

| Abstract: | The optimal attitude control of motion planning for a system of underactuated coupled rigid bodies subject to a universal joint is discussed in this paper.Because the number of the control inputs are less than the number of degree of freedom,when the angular velocity of the universal joint is the control input of the spacecraft system,the attitude motion of the system becomes a typical nonholonomic one,and the dynamics and control problem of the motion planning become very complicated.Particle Swarm Optimization on spacecraft attitude of nonholonomic motion planning is proposed according to the optimal control theory.The effectiveness of the approach is shown by numerical simulation. |
