    Abstract:

    Here,an event-triggered γ sliding mode control scheme is proposed for the second-order leader-follower multi-agent systems with unknown nonlinear functions.First,a novel sliding mode reaching law based on inverse hyperbolic sine function is selected to ensure that the multi-agent system achieves consensus in limited time.Second,a sliding mode function with gain scaling factor γ is designed and the event triggering mechanism is introduced.Through Lyapunov stability analysis,it is proved that the proposed control scheme is effective,which can not only eliminate the system chattering but also reduce the sampling frequency of the control action.In addition,the minimum lower bound of the triggering time interval is proved,which excludes Zeno phenomenon.Finally,the effectiveness of the proposed scheme is verified by Matlab/Simulink simulation results.
