In “Comments on Constrained Infinite-Horizon Model
Predictive Control for Fuzzy-Discrete-Time Systems” (IEEE Trans.
Fuzzy Syst.), Ding criticized that the application of Lyapunov
method, the handling of the output constraint, and the resultant
linear-matrix-inequality-optimization problem are incorrect
in IEEE Trans. Fuzzy Syst., vol. 18, no. 2, pp. 429–436, Apr. 2010.
This rebuttal answers some key points raised in the comments.
