The event-triggered finite-time \({{H}_{\infty }}\) control based on bumpless transfer for switched neutral systems is investigated in this paper. To alleviate the communication burden, an event-triggered mechanism is proposed. The control bumps caused by switching and triggering instants may result in the deterioration or even failure of transient performance. A bumpless transfer control strategy is proposed to reduce the mixed bumps. Then, by employing multiple Lyapunov functions and mode-dependent average dwell time methods, sufficient criteria are obtained to ensure finite-time boundedness of the closed-loop system with \({{H}_{\infty }}\) performance and event-triggered bumpless transfer performance under the proposed controller. Furthermore, the lower bound of the triggering interval is analyzed in detail to exclude Zeno behavior. Finally, the proposed method is validated for feasibility and effectiveness through two examples.
