Abstract

This paper focuses on achieving prespecified-time stability in maglev suspension systems. Within a sliding mode control framework, we design three types of controllers for finite-time, fixed-time, and prespecified-time convergence. Pole assignment techniques are utilized to precisely tailor the system dynamics on the sliding manifold. The theoretical findings are validated through numerical simulations, which highlight the practical benefits of the proposed control strategies.
