摘　　要：无人机编队在环境或任务发生变化时,需要进行编队重构。在对无人机编队重构安全控制问题进行分析的基础上,采用分布式模型预测控制(DMPC)的思想,将重构问题转化为一系列在线优化问题。结合安全性约束条件建立其重构代价函数,提出一种基于改进微分进化的分布式模型预测控制算法(DE-DMPC)求解每个时域内的代价函数优化问题。通过仿真证明,该算法能够实现编队重构安全控制,且较标准微分进化算法性能更好。Flight formation of multiple UAVs needs to be reconfigured when the environment changes ormissions are modified. Based on the analysis of safety problem during reeonfiguration, the process istransformed into a series of on-line optimizations using distributed model predictive control （ DMPC ）. Afterthe setup of cost function with safety restriction taken into consideration, a distributed model predictivecontrol algorithm based on modified differential evolution （DE-DMPC） is put forward to deal with theoptimization problems at each interval. Simuilations show the effectiveness of the DE-DMPC algorithmfor reconfiguration safety control. The algorithm is superior to the standard DE algorithm in terms ofperformance.
