摘要多智能体系统凭借很强的鲁棒性能和可扩展能力在军用和民用领域得到了广泛的应用。首先,本文以连续二阶多智能体系统为研究对象,设计了无时延和有常时延两种情况下的一致性协议,最终实现编队控制。在实际系统中,由于通信带宽限制及环境的约束,系统必然存在时变时延。之后,本文研究了具有时变通信时延的多智能体系统的分布式编队控制问题,探讨了控制协议中的参数对系统收敛性以及系统所允许的最大通信时延的影响。以上的研究都是针对连续系统。接着本文研究了离散的多智能体系统,followers跟踪时变参考状态,给出了系统实现编队和达到速度一致时协议所含参数必须满足的充分条件。最后利用matlab仿真验证所设计的一致性协议的有效性。64512

Title The distributed consensus of multi-agent systems and its application——the distributed formation control
Abstract By virtue of high robustness and scalability, Multi-agent system are widely used in military and civil fields.Firstly,this paper have studies the second order consensus system.It has designed two kinds of consistency protocol, one with time delay and another without.Finally,It has realized the formation control.Due to the communication bandwidth limitation and the constraints on environment, there must be time-varying delay in the actual system.Then,This paper also have studied the distributed formation of multi-agent systems with time-varying communication delay,probed into the influence of parameter in control protocol on the system’s convergence and the maximum communication time delay which permitted by the system.The above studies are focused on the continuous system.Then,this paper studies the discrete time multi-agent system with the followers track the variable reference state.It also have given the sufficient conditions that the parameters in consensus protocol should satisfy in order to realize formation and reach consensus speed.At last,simulation results illustrate the correctness of the designed consensus protocol.
