Abstract: A decentralized adaptive event-triggered funnel control for a class of uncertain large-scale nonlinear systems is studied. Firstly, a new adaptive decentralized funnel controller was constructed by using a new funnel control method with barrier Lyapunov function to achieve output tracking for a given transient behavior. Secondly, an auxiliary nonlinear function was introduced to solve the interconnection problem in controller design. At the same time, the command filtering technique was applied to backstepping design to avoid ‘complexity explosion’ in backstepping process. In addition, an event-triggered mechanism was designed to reduce unnecessary transfers between controllers and actuators, thus improving resource efficiency. The results show that the proposed control scheme can ensure that all the signals of the closed-loop system are bounded and the tracking error always evolves in the funnel. Finally, the effectiveness of the control method is verified by a numerical system.

Key words: large-scale nonlinear, funnel control, event-triggered control, command filter technology
