摘要: In this paper, novel stability conditions for Takagi-Sugeno (T-S) fuzzy systems are presented. The so-called nonquadratic membership-dependent Lyapunov function is first proposed, which formulated in a higher order form of both the system states and normalized membership functions than existing techniques literature. Then, new developed by approach. It shown that conservativeness obtained criteria can be further reduced as degree increases. Two numerical examples given to demonstrate effectiveness less theoretical results.
