Modelling and Control of a Non-Isolated Boost DC–DC Converter Using Voltage Lift Technique

This article presents modelling and control strategies to the non-isolated Boost DC-DC converter using voltage lift technique proposed by Shahir [1], which have not been developed until the present moment. Thus, the performance of the converter is evaluated when using different topologies of controllers: Integrative (I), Proportional-Integrative (PI), Proportional-Integral-Derivative with additional pole
$(\mathbf{PID}+\mathbf{p})$
and a combination of PID, PD
²
and three additional poles
$(\mathbf{PID}+\mathbf{PD}^{2}+\boldsymbol{3}\mathbf{p})$
. Steps and insights are provided for selecting, designing and validating the controllers. The results shows the effectiveness of each controller under four different scenarios: step change of load, voltage reference and input voltage, also evaluating measurement noise rejection capability.
