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。
Research on Attitude Control of Rigid Spacecraft with Two Momentum Flywheels. When the system angular momentum is zero, the system control problem can be transformed into the nonholonomic motion planning problem of drift-free system. The particle swarm optimization algorithm for motion programming control with two momentum flywheel spacecraft attitude is proposed by using the optimal control method and spline approximation technique. Optimal control of motion planning is smooth, and the initial value and the final value are zero, you can easily through the servo motor flywheel control. The numerical simulation shows that this method is effective for spacecraft attitude and motion planning and control.
