摘要：
In this paper, an improved sliding mode control algorithm based on extended state observer is proposed for the influence of system uncertainties such as load resistance disturbance and input voltage change on the output voltage of Boost converter. Firstly, the extended state observer is designed to estimate the system state, load resistance and input voltage. Then, based on the estimated value, the improved sliding mode control algorithm is used to design the system controller. Through theoretical analysis, the stability of the closed-loop control system of Boost converter is proved. The simulation and experimental results show that compared with the traditional sliding mode control algorithm, the proposed control algorithm can better improve the tracking performance and the robustness of the system. © 2023 South China University of Technology.
