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)
