Event-triggered finite-time stabilization of maglev system with suspension air gap constraint

This paper investigates the finite-time stabilization of maglev system with suspension air gap limitation utilizing event-triggered technique. A subtle event-triggered controller is constructed on the basis of a finite-time trigger mechanism with a time-varying threshold and tangential barrier function. This control algorithm ensures that the suspension air gap is limited to a specific vicinity while the states of the maglev system converge to the origin within a finite time. The contribution lies in the fact that the resources consuming is reducing effectively while the design and the theory analysis for the constrained and unconstrained suspension air gap are unified. Finally, the practical simulation validates the efficiency and superiority of the proposed approach.
