| 英文摘要 |
| 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. |
