This paper studies the problem of multi-leader multi-follower coordination with proximity-based network topologies. The particular interest is to drive all the followers towards the convex hull formed by the moving leaders while producing cohesion behavior and keeping group dispersion. First, in the case of stationary leaders, we design a gradient-based continuous control algorithm. We show that with this continuous algorithm the control objective can be achieved, and the tracking error bound can be controlled by tuning some control parameters. We apply the continuous control algorithm to the moving leaders case and show that the tracking error bound is related to the velocities of the leaders. However, in this case, the algorithm has one restriction that the velocities of the leaders should depend on neighboring followers’ velocities, which might not be desirable in some scenarios. Therefore, we propose a nonsmooth algorithm for moving leaders which works under the mild assumption of boundedness of leaders’ velocities. Finally, we present numerical examples to show the validity of the proposed algorithms.

在约定采访的餐厅里,李昂坐在椅子上,支起腰,使劲眨眨眼,抬手揉了揉太陽穴,若隐若现的黑眼圈难掩疲惫。短暂的振作精神之后,他又滔滔不绝起来。  他刚开完会,直到晚上8点,他才有空借着采访时间坐下来好好吃一顿饭。  从微博账户“解说李九粉丝后援会”每周公布的“九哥一周行程表”来看,李昂每天的行程都被安排得满满当当。在KPL比赛期间,解说作为基本工作占据了大部分时间,除此之外则是在虎牙固定的游戏直播、《
