N2 - Since the output voltage of the renewable energy sources generally varies with the load power, a dc-dc converter is essential to regulate the output voltage and match the load demand. To improve the voltage tracking performance and enhance the robustness of the converter, a composite fast terminal sliding mode (FTSM) controller based on the linear extended state observer is proposed in this paper. The observer is utilized to estimate the lumped disturbance of converter, including parameter variations and load disturbance. The FTSM controller is designed to regulate the output voltage of the converter, which can get rid of the singularity problem and suppress the chattering issues. It is shown by Lyapunov stability theory that the system states can converge to the reference values within finite time. Finally, the effectiveness of the controller is verified by simulation and experimental results.
