  4. Abstract:
  5. In this letter, it is verified that the main result of the above article [1] on converging the voltage tracking error of a buck converter controlled by a fractional-order sliding mode controller cannot be logically justified. The root cause of this inconsistency, which is an improper use of an inequality, is discussed. © 2004-2012 IEEE
