In this paper, a robust dual loop control strategy based on the flatness properties and disturbance estimations is proposed for the non-ideal Boost converter under the unknown external disturbances. By means of the flatness based control approach, an outer loop for the output voltage regulation and an inner loop for the inductor current tracking are designed in detail. Meanwhile, taking into account the model losses of the non-ideal Boost converter and the flatness based control is a model control method, the disturbance observers are constructed to calculate the input voltage and the output current for avoiding the use of the sensors. In order to validate the feasibility and robustness of the proposed control scheme as well as the estimated accuracy of the disturbance observers, various simulations in the presence of sinusoidal input voltage perturbations and sinusoidal load resistance disturbances are realized.
