we investigate the problem of consensus in leader-following multi-agent system
where the information of the leader is only accessed by a subset of the following agents. For the part of the follower who cannot obtain the leader’s information
the state of the leader need to be estimated. In addition
considering the discontinuity of obtaining the output information of agents under certain conditions
an impulsive observer is introduced to reduce the sampling times among multiple agents. To achieve this
this paper aims to design a controller based on impulsive observer to achieve the consensus of leader-following multi-agent systems. Firstly
an impulsive full-order observer and a consensus protocol are designed for each follower
so that the follower can use the observer to estimate the leader. Secondly
the dynamic equation of the error system is derived
and the appropriately Lyapunov function is constructed by using the error variables. Finally
the stability of error systems is studied by using the Lyapunov stability theory combining with the linear matrix inequalities
so that the sufficient conditions for the leader-following consensus problem of multi-agent systems can be obtained. Numerical simulation results clearly show the effectiveness of the proposed controller.
