摘　　要：针对航天器编队在推力约束和通信约束下的相对位置协同控制问题,给出一种参数寻优下的反步滑模协同控制方法,实现了航天器编队的位置跟踪控制。基于非线性的相对动力学方程,考虑控制器推力约束和编队航天器之间的通信限制,利用图论知识,设计反步滑模协同控制器,并采用基于模拟退火的粒子群算法对控制器参数进行寻优,最后通过仿真验证控制算法的有效性。仿真结果表明,与一般的滑模控制相比,本文的控制方法具有更好的位置跟踪性能,可以实现卫星编队对参考轨迹的跟踪控制,具有较好的抗干扰能力。A backstepping sliding mode control method based on parameter optimization is proposed for the coordinated control of spacecraft formation relative position.Based on the nonlinear relative dynamic equations,a consistency-based backstepping sliding mode controller is designed considering the thrust constraints of the controller and the communication constraints between the formation spacecraft,and a particle swarm optimization algorithm based on simulated annealing is used to optimize the controller parameters.The simulation results show that the proposed control method has better position tracking performance than general sliding mode control,and can achieve high precision tracking control of satellite formation to reference trajectory.
