Adaptive Global Sliding Mode Controller Design for Perturbed DC-DC Buck Converters

This paper proposes a novel adaptive intelligent global sliding mode control for the tracking of DC-DC buck converter with time-varying uncertainties/disturbances. The proposed law is formulated using switching surface that eliminates reaching phase and ensures existence action from start. derived based on Lyapunov stability theory. effectiveness approach illustrated via high-fidelity simulations by means Simscape simulation environment in MATLAB. Satisfactory accuracy, efficient suppression chattering phenomenon input, high robustness against uncertainties/disturbances are among attributes approach.
