研究了一类带扰动的不确定多智能体系统的一致性问题。首先,利用局部状态信息建立状态和扰动观测器,对状态和扰动进行估计,利用估计值消除扰动。其次,将动态事件触发机制应用于一致性控制协议的设计过程中。引入事件触发机制,只有在满足触发条件时进行控制器更新,可以明显减少系统的触发量。最后,构造出不确定多智能体系统的一致性控制协议。引入自适应动态控制参数,利用与事件误差相关的自适应律对参数进行调整,避免了对全局信息的依赖。同时,利用李雅普诺夫(Lyapunov)稳定性理论证明了所提出的控制协议是稳定的,所设计的动态事件触发机制不具有芝诺(Zeno)行为。仿真实例验证了算法的有效性。
Event-triggered adaptive consensus control for uncertain multi-agent systems
The consensus problem for general uncertain multi-agent systems with disturbance was investigated.Firstly,the observer of the state and disturbance were established by utilizing the local state information to estimate the state and disturbance,and then the estimated value was used to eliminate the disturbance.Secondly,a dynamic event-triggered mechanism was applied in the process of consistency controller design.By introducing event-triggered mechanism,the controller was only updated when the triggerring conditions were met,and the amount of triggering in the system can be significantly reduced.Finally,a consistent control protocol for uncertain multi-agent systems was constructed.The adaptive dynamic control parameter was introduced,which can be adjusted using an adaptive law related to the event error to avoid dependence on global information.Meanwhile,it is proved through Lyapunov stability theory that the proposed control protocol is stable,and the designed dynamic event-triggered mechanism does not have Zeno behavior.Simulation examples verified the validity of the proposed algorithm.
