Design of Global Sliding-Mode Controlled Buck Converters Based on Equivalent Control

  • Received Date: 12 Mar 2008

  • To simplify the design of sliding-mode controller and improve the robustness of converter systems,the principle and design method of global sliding-mode control were investigated and introduced to the controller design for Buck converters.The main characteristics of Buck converters with global sliding-mode control were analyzed,the design procedure of global sliding-mode controller was given based on the equivalent control idea,and global sliding-mode control law was designed.Finally,a simulation was carried out to explore the feasibility and validity of applying the global sliding-mode controller to Buck converters.The simulation results show that a Buck converter with the global sliding-mode controller has a high transient response velocity than a Buck converter with the conventional sliding-mode controller,and the former possesses global robustness throughout the transient process.
