Finite-time control of direct current–direct current boost converters in the presence of coil magnetic saturation

Abstract

This paper focuses on the global stabilization problem of controlling direct current–direct current switched power converters in the presence of coil magnetic saturation. A finite-time controller is investigated for the modified nonlinear system model by utilizing an adding a power integrator technique. With the finite-time control scheme, not only a faster convergence rate is obtained, but also better suppression ability to the inevitable disturbances is achieved for the closed-loop system. Simulation comparison results show the effectiveness of the proposed method.
