| 摘 要： | 研究带有两个动量飞轮的刚体航天器姿态控制问题。在系统角动量为零的情况下,系统的控制问题可转化为无漂移系统的非完整运动规划问题。利用最优控制方法和样条逼近技术提出求解带有2个动量飞轮航天器姿态的运动规划控制的粒子群优化算法。运动规划的最优控制是光滑的,且初值和终值均为零,可以方便地通过伺服电机实现飞轮的控制。数值仿真表明:该方法对航天器姿态运动规划控制是有效的。

| Abstract: | The attitude control of a rigid spacecraft with two momentum wheel actuators is discussed.The control problem of the system can be converted to a nonholonomic constraint motion planning problem of a drift-free system with non angular momentum.A particle swarm optimization(PSO) algorithm of a spacecraft attitude motion planning with two momentum wheel actuators is proposed by using optimal control method and the spline approximation technique.The optimal controls are smooth and the initial values and termina... |
