ABSTRACT = {In this paper, the stabilization problem of an observer-based T-S fuzzy 
time-delay system under imperfect premise matching is studied, in which the T-S 
fuzzy observer model with time-delay and the fuzzy controller do not share the 
same membership functions. The objective is to design a state observer and unmatching fuzzy controller such that the closed-loop system with time-delay is 
asymptotically stable. A sufficient condition for the stabilization via observerbased state feedback under imperfect premise matching is presented, and an 
observer-based state feedback controller under imperfect premise is also 
constructed. The proposed control scheme is well capable of enhancing the design 
flexibility, because the membership functions of the observer-based controller can 
be arbitrarily selected. A few numerical examples are given to illustrate the 
effectiveness and advantages of our design method.},
