Abstract: The performances of wireless mobile portable devices are constantly improving, and the response speed and robustness of the device power supplies need to be researched. In general, wireless devices are powered by batteries, which require various Buck converters. In order to improve the response speed and robustness of the Buck converter, a smooth terminal sliding mode (TSM) control method is proposed. The TSM surface and the control law are designed. The sliding mode existence condition is proved theoretically, and the robustness of the closed-loop system under disturbance is analysed. The smooth TSM overcomes the chattering phenomenon that occurs in the traditional TSM, so a fixed-frequency pulse width modulation can be realised, which will have a good application prospect. The simulation results show that the proposed control method has the advantages of fast dynamic response and strong robustness.
