This paper proposes output feedback control for
fuzzy descriptor systems with interval time-varying delay. First,
singular nonlinear dynamic systems with interval time-varying
delay are taken into consideration. Then using a Takagi-Sugeno
(T-S) fuzzy model, we design a fuzzy representation of the original
nonlinear system. This fuzzy representation consists of local
linear descriptor systems. To achieve the control objective, a fuzzy
controller and observer is designed in a systematic manner. The
stability analysis of the overall closed-loop fuzzy system leads
to formulation of linear matrix inequalities. Using the observer
and controller gains by solving LMIs, we carry out numerical
simulations which verify theoretical statements.
