Comment on “Fractional-order fixed-time nonsingular terminal sliding mode synchronization and control of fractional-order chaotic systems”

This comment is to point out to mistakes made in the paper (Ni et al. in Nonlinear Dyn 89:2065–2083, 2017 ). It is shown that the proofs of the stability of reaching and sliding phases given in the mentioned paper are not acceptable. Furthermore, the reported simulation results contradict with fract...

Zusammenfassung:This comment is to point out to mistakes made in the paper (Ni et al. in Nonlinear Dyn 89:2065–2083, 2017 ). It is shown that the proofs of the stability of reaching and sliding phases given in the mentioned paper are not acceptable. Furthermore, the reported simulation results contradict with fractional calculus. This is evidenced by resimulating the example 1 of the paper.
