Abstract
This article proposes a novel event-triggered second-order sliding mode (SOSM) control method for uncertain nonlinear systems. First, three saturated-like functions are predesigned to construct a new switched triggering mechanism. Under the proposed triggering mechanism, an event-triggered SOSM controller is designed to ensure that the states of the SOSM system finite-time converge to a domain of the origin and never escape from the domain. Then, to avoid Zeno behavior, two positive minimum inter-execution intervals are obtained based on different triggering conditions. Finally, a simulation study is given to verify the effectiveness of the control strategy.
