摘要
电磁编队飞行具有广泛的应用前景。针对电磁编队的重构问题,首先建立了六自由度的相对运动模型,从而实现编队相对位置和相对姿态的协同控制。编队的重构问题可视为最优控制问题,可通过伪谱法将其转化为有约束的非线性规划问题。针对系统的非线性和耦合性,提出了一种高精度的数值解法,用于重构轨迹的生成。仿真结果验证了该方法的有效性。
A 6-DOF relative motion model taking into account the inherent electromagnetic coupling is established to achieve synchronous control of both the relative translation and rotation in the array. Considering the reconfignration of electromagnetic formation flying as an optimal control problem, it is transformed into a constrained non-linear program through the Legendre pseudospectral method. A novel high-precision numerical computation method is developed against the strong nonlinearity and coupling of the system. Feasible trajectories are generated to verify the validity of the proposed dynamic model and optimization algorithm.
