Abstract

This paper focuses on the design of event-triggered observer-based heterogeneous memory controllers for leader-following multi-agent systems with time-varying topology. In order to save limited on-board resources, a novel adaptive event-triggered strategy based on the nonlinear transformation law of the estimation error is proposed in this paper, which can effectively reduce some unnecessary data transmission due to small fluctuations after the estimation error converges. Then, a more general topology structure described by an interval type-2 fuzzy model is adopted, which contains both nonlinear time-varying law and uncertain parameters. Taking into account the differences in the interactions between various agents, the heterogeneous fuzzy-dependent controllers with past state measurements are constructed to further improve consensus performance. Moreover, some sufficient conditions are derived to solve the designed observers and controllers while ensuring that the desired consensus of the multi-agent systems can be achieved. Finally, two examples are given to illustrate the superiority and effectiveness of the proposed event-triggered strategy, and also to verify that introducing past state measurements into the controller helps enhance the consensus control performance.
具有时变拓扑和通信约束的多智能体系统的基于记忆的一致性控制。
针对具有时变拓扑结构的leader-follow多智能体系统,研究了基于事件触发观测器的异构存储器控制器的设计。为了节省有限的机载资源,本文提出了一种基于估计误差非线性变换规律的自适应事件触发策略,可有效减少估计误差收敛后由于波动小而产生的不必要的数据传输。然后,采用区间2型模糊模型描述更一般的拓扑结构,该拓扑结构既包含非线性时变规律,又包含不确定参数。考虑到不同智能体之间相互作用的差异,构造了具有过去状态测量值的异构模糊依赖控制器,进一步提高了共识性能。在此基础上,给出了求解所设计的观测器和控制器的充分条件,同时保证了多智能体系统能达到期望的一致性。最后,给出了两个例子来说明所提出的事件触发策略的优越性和有效性,并验证了在控制器中引入过去的状态测量有助于提高共识控制的性能。
