摘要

This paper further studies stabilization and state feedback H∞, control con ditions for discrete T-S fuzzy systems. By extending a nonquadratic Lyapunov function and applying a nonparallel distributed compensation (non-PDC) control law, first a re laxed stabilization conclusion is presented that is an extension of some previous results in the literature, then a sufficient condition which can guarantee the existence of state feedback H∞ controllers for the T-S fuzzy systems is proposed. In comparison with the existing results, the proposed conditions not only provide more relaxation but also ensure better H∞ performances. Finally, the validity and applicability of the proposed results are successfully demonstrated through two numerical examples.
