Iss., 1854-1858 (2008). 2008 Tsinghua University, Beijing ZH T-S fuzzy systems buck converter fuzzy sliding mode control Summary: A T-S fuzzy model for a buck converter with nonlinear characteristics in Continuous Current Mode (CCM) is developed to improve the application of buck converters in controllers. A fuzzy sliding surface based on the T-S fuzzy model using Lyapunov function and the Linear Matrix Inequality (LMI) method accounts for uncertainties in system parameters and exterior disturbances. Simulations indicate that the buck converter with the fuzzy sliding mode controller provides good tracking performance with strong interference rejection with rise and regulating times of about 15ms.
