| 摘 要： | 1 IntroductionDuring the last decade, the robust stability andstabilization problem for uncertain dynamic systemswith time delay have received much attention. Manyarticles focusing on time-delay systems have beenreported 1-4]. Delays frequently lead to instability andare sources of oscillations in many systems. For ex-ample, the trivial solution of the equationasymptotically stable, but thatof the equation for neutral systemunstable for any delayd > 0, so the study of the stability of neutral…

| Abstract: | The problem of guaranteed cost fuzzy controller is studied for a class of nonlinear time-delay neutral systems with norm-bounded uncertainty based on T-S model. The sufficient conditions are first derived for the existence of guaranteed cost fuzzy controllers. These sufficient conditions are equivalent to a kind of linear matrix inequalities. Furthermore, a convex optimization problem with LMI constraints is formulated to design the optimal guaranteed cost controller. |
