In this paper, instead of the time-invariant state-space representation in the consequent of the T-S fuzzy model, tim,e-varying system is considered in order to deal with the reconstruction error between the real system to be controlled and its T-S model, and fuzzy approximator is employed to cope with unknown functions involved in the model. As a result, it reaches an adaptive controller that has two parts: one is obtained by solving certain linear matrix inequalities (LMIs) (fixed part) and another one is acquired by the fuzzy approximator in which the related parameters are tuned by adaptive law (variable part). The proposed controller can guarantee the closed-loop system to be asymptotically stable.
