Abstract: Background: DC-DC Boost Converters are crucial components in solar power systems, requiring effective control for optimal performance. This paper introduces an adaptive sliding mode controller with a modified sliding function to overcome the limitations of classic sliding mode control in DC-DC boost converters.
Materials and Methods: The study presents a detailed mathematical model of the DC-DC boost converter and derives a state-space representation. A Proportional-Integral (PI) type sliding function is proposed, introducing an additional tuning parameter γ that can be adaptively adjusted based on load variations. The control law and existence conditions for sliding modes are established, demonstrating the robustness of the proposed method to load changes.........
