Abstract
A robust auto-disturbance-rejection controller (ADRC) for phase-shifted resonant converters is proposed. The variation of load resistance is observed and estimated by an extended state observer, which is the core of the ADRC. A dedicated nonlinear state error feedback is proposed to synthesise the control actions to obtain superior dynamic performance. Laboratory experiments based on a Matlab/DSP system have been carried out and the results confirm the robustness of the controller
