Comments on "H∞ synchronization of uncertain fractional order chaotic systems: adaptive fuzzy approach" [ISA Trans 50 (2011) 548-556].

In this note, we demonstrate that the stability analysis in the main theorem of the paper [Lin T-C, Kuo C-H. H(∞) synchronization of uncertain fractional order chaotic systems: adaptive fuzzy approach. ISA Trans 2011;50:548-56] is wrong.
