作者： Nankai Chen Yaonan Wang Lin Jia School of Electrical and Information Engineering Hunan University

According to the characteristics of nonholonomic mobile robot kinematics model,this paper analyzes the changes of topology among multi-mobile robots,and proposes a distributed formation control ***,the dynamic and kinematics equations of the multi-mobile robot system are analyzed,and a distributed estimation strategy for system stability is proposed under the condition of fixed ***,considering the stable switching topology,the globally uniform exponential convergence conditions of leader-follower formation system are studied by Lyapunov ***,the upper and lower bounds of the convergence time of hybrid switching systems are determined by the mean delay time *** results show that these method are feasible.
