Abstract

This paper proposes a robust active disturbance rejection control (ADRC) scheme for a push–pull DC–DC converter, addressing challenges posed by parameter uncertainties, load variations, and external disturbances. Unlike most existing studies on other converter topologies, this work develops and validates an ADRC controller specifically designed for the push–pull converter. First, the average model of the converter is presented, and then the system’s flatness property is used to design an ADRC controller based on a linear extended state observer (LESO) for total disturbance compensation. Next, a Lyapunov-based stability analysis proves the ultimate boundedness of the observer and tracking errors using a separation argument. Simulation and experimental results validate the effectiveness and superior performance of the proposed controller compared to proportional–derivative (PD) and proportional–integral–derivative (PID) controllers under various operating conditions, providing a fair comparison rarely addressed in existing studies, while maintaining the same control loop specifications.
