Encircling exceptional points (EPs) is of great significance in studying topological properties in non-Hermitian systems; however, non-adiabatic transitions pose a major challenge to the continuous dynamically encircling of EPs. This work presents a scheme for the dynamically encircling of EPs through phase-tracked closed-loop control, enabling the smooth evolution along the eigenfrequency Riemann surface.
