This paper proposes a Luenberger-type fuzzy observer for
perspective systems. First, the T-S fuzzy model for perspective systems is proposed for a fuzzy observere sign.
Then, the fuzzy observer of perspective systems is designed
to estimate the unmeasurable states, where the estimation
gains are obtained by solving a set of linear matrix inequalities(LMIs). This observer scheme gives the estimated
states converging to the real states exponentially. The stability analysis is formulated based on the Lyapunov direct
method. The proposed observer yields asymtotic estimates
of the unmeasurable states and is signiﬁcantly simpler than
existing nonlienar observer design. Finally, numerical simulations are carried out to verify the theoretical results and
show satisfactory performances.
