Comparison of the behavior of voltage mode, V2 and V2Ic control of a buck converter for a very fast and robust dynamic response

This paper proposes an optimization method to design the parameters of controls for power converters in order to achieve a very fast dynamic response while remaining stable and robust over the desired operation region. The proposed optimization algorithm is applied to different analog controls and is used to compare the dynamic response of the Voltage mode, V² and V²I_c control for different cases in order to evaluate which control presents the best performance in terms of dynamic response and stability robustness to system tolerances.
