Abstract :
Focused on the normal architecture of buck DC switching-mode power supply, this paper presents the system modeling, the model parameter differences as a result of dynamic load changes and the reason of the poor stability on light load condition are analyzed. To improve the dynamic performance on the robustness for the system model parameter uncertainty and the system stability of light load condition, this paper proposes an adaptive stabilization control algorithm and its controller tuning method, which is simple and easy to implement. The Matlab simulation and application results show the good control performance
