title: Comments on "Output tracking and regulation of nonlinear system based on Takagi-Sugeno fuzzy model".
abstract: In the above paper, a Takagi-Sugeno (T-S) fuzzy-model-based output regulation methodology is proposed. However, since the problem formulation is incorrect, the derived design techniques may not accomplish the control objectives. We illustrate the reasons and show counterexamples.
