摘要:

针对存在输入时滞的多智能体系统(multi-agent system,MAS)滞后一致性问题,提出一种基于时基生成器(time base generator,TBG)的二阶MAS预设时间领导跟随滞后一致性控制方法,使得稳定时间与系统初始状态无关且可预先设定。首先,提出一种误差变换方法,将具有时滞的误差系统转换为无时滞误差系统。然后,利用TBG函数构造误差辅助变量并构造相应滑模面,进而设计预设时间控制器。同时,证明所设计控制器的预设时间稳定性。最后,通过数值仿真验证所提方法的可行性及有效性。仿真结果表明,MAS能够实现精确的预设时间滞后一致性。

Abstract:

To solve the lag consensus problem of multi-agent system (MAS) with input delay, a second-order MAS predefined-time leader-following lag consensus control method based on time base generator (TBG) is proposed, which makes the settling time independent of the initial state of the system and can be predefined in advance. Firstly, an error transformation method is proposed to transform the error system with delay into the delay-free error system. Secondly, the TBG function is used to construct the error auxiliary variable and construct the corresponding sliding mode surface. Then, the predefined-time controller is designed and the stability of the predefined-time controller is proved. Finally, the feasibility and effectiveness of the proposed method are verified by numerical simulation. Simulation result shows that the MAS can achieves accurate predefined-time lag consensus.

Key words: multi-agent system (MAS), predefined-time lag consensus, input delay, time base generator (TBG)
