Abstract
This paper investigates the finite-time stabilization for a class of nonlinear systems by proposing a new event-triggered controller. The novelty lies in that, by introducing an exponential term, the control gains are exponential alterable in the interval of two adjacent event instants. Moreover, based on the proposed controller, a specific event-triggered scheme with a new type of error function is also derived to stabilize the concerned system in a finite time. In addition, a positive lower bound of the inter-execution is obtained, such that the Zeno behaviors can be avoided. Finally, illustrative examples are provided to verify that the overall amount of triggered events can be reduced by utilizing the proposed method in this paper.
