“…Thus, T-S fuzzy systems (TSFSs) can be addressed by typical methodologies based upon linear system methods [10]. TSFS based methods play a significant role in stability and performance analysis, controller design, and observer design for nonlinear systems, see [38,21,37,36,25] and the references cited therein for example. Recently, T-S fuzzy modeling methods and fuzzy model based control techniques have been extended to nonlinear 2-D systems in [22,26].…”
