The mean square bounded consensus problem of multi?agent systems under deception attacks was studied， and an event?triggered impulsive control method with upper bound of trigger time was designed based on the fixed?time impulsive control and event?triggered mechanism. By utilizing the Lyapunov stability theory， graph theory， and linear matrix inequality techniques， the sufficient conditions for the mean square bounded consensus of the multi?agent systems were obtained. Moreover， it was verified that the proposed event?triggered impulsive control method can automatically adjust the impulsive time intervals， and realize the secure consensus quickly. Finally， the numerical simulation results further verified the validity of the theoretical results.
