From the aspects of modeling, stability analysis, and controller design, the current research status of the type-1 T-S fuzzy control and the interval type-2 T-S fuzzy control are reviewed, with an overall elaboration on the conservativeness issue in analysis and design of type-1 T-S fuzzy systems, type-1 T-S fuzzy polynomial systems, and interval type-2 T-S fuzzy systems. A discussion is also made on the principles of the slack variable approach, the parameter dependent Lyapunov function approach and the membership-function-shape-dependent approach, as well as their applications to reduce conservativeness of the fuzzy feedback controller. In addition, from the aspects of modeling of type-1 T-S fuzzy systems and the parameter dependent Lyapunov function design approach of interval type-2 T-S fuzzy systems, prospects on the T-S fuzzy control are described. The further research directions may include the output feedback control of type-1 T-S fuzzy polynomial systems, the interval type-2 T-S fuzzy systems with time-delays, the robust control and model reduction of interval type-2 T-S fuzzy systems, and the hardware implementation and engineering applications of the proposed approaches.
