Comments on “Fuzzy-Model-Based Quantized Guaranteed Cost Control of Nonlinear Networked Systems”

This letter indicates that there exist some fatal errors in the work of R. Lu, H. Cheng, and J. Bai, “Fuzzy-model-based quantized guaranteed cost control of nonlinear networked systems,”
IEEE Trans. Fuzzy Syst.
, vol. 23, no. 3, pp. 567–575, Jun. 2015, that is, the main result (Theorem
2
) and inequality (29) in this work are incorrect. Thus, the proposed approach to stabilizing nonlinear networked systems is vacuous.
