This study analysed the output voltage control and performance of a DC–DC boost converter. The focus is on the continuous conduction mode of a DC–DC boost converter and each component is designed and selected for circuit assembly. A small‐signal AC model based on a pulse‐width modulated DC–DC boost converter is constructed, and four control algorithms, namely the ‐integral control, deadbeat control, linear quadratic regulator control, conventional active disturbance rejection control and new compensated active disturbance rejection control are put forward to regulate the converter output voltage when faced with immeasurable input and load disturbance. The paper emphasises the objective steering the output voltage to its reference with fast response, little overshoot, and ripples. The equivalent input disturbance observer is utilised to compensate for the tracking error existing in the observed system. Scenarios for validation are investigated in MATLAB/Simulink environment and LabVIEW‐based field‐programmable gate‐array experimental rig. The results indicate that the proposed method has the best rejection effect on the above‐mentioned system disturbances with stability improvement.
