摘要

This paper presents an Adaptive Sliding Mode Control (ASMC) based on a Hyperbolic Tangent Function (HTF) in combination with an extended state observer for the output voltage regulation of the buck-boost power converter. Firstly, due to the unique condition and sufficient for the existence of the sliding mode, the buck-boost power converter’s robustness, and chattering reduction, employing the use of the HTF into the adaptive sliding mode control is derived. After, a linear extended state observer designed to estimate the unknown parameters of the power converter, which adapted to the ASMC. In this way, the proposed ASMC law minimizes the sliding surface chattering, as well as the sudden output load changes. Therefore, we guarantee that all the buck-boost variables, and input control responses present a better performance than a Traditional Sliding Mode Control (TSMC). Finally, Matlab-Simulink/PSIM simulations and experimental results verified the correctness and effectiveness of the proposed control algorithm.
