Abstract
To address the issue of poor dynamic regulation caused by uncertainties and disturbances in the external conditions of the High step-up quasi-Z-source dc-dc boost converter (HSQZSC) control system, an integral sliding mode (ISM) controller is designed to ensure system robustness and fast response. Firstly, the operating principle of HSQZSC is analyzed to establish a mathematical model. Secondly, a sliding surface is designed using the output voltage error, inductor current error, and their integrals as state variables. Then, the conditions for stable operation of ISM are derived, and the parameter design is analyzed. Finally, by comparing with conventional control strategy using simulation and experimental platform, the results demonstrate the feasibility and effectiveness of the designed ISM control strategy.
