Comment on “PWM-Based Adaptive Sliding-Mode Control for Boost DC–DC Converters” [Aug 13 3291-3294]

Abstract

The purpose of this paper is to comment on the reference voltage tracking ability of a recently proposed state observer based adaptive sliding mode control for boost converters. It is shown that the control in the cited paper cannot track the reference voltage. A modified control law that enables reference voltage tracking while preserving the other advantages of the commented paper is proposed and validated by simulation and experimentation on laboratory hardware.
