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, V
