T-S fuzzy controllers for a class of nonlinear systems with uncertainties and input delay

This paper deals with stability analysis and control designs for a class of delay-dependent nonlinear systems with input constraint when using the T-S fuzzy model in consideration of the uncertainties in the system. As a result, it arrives at two kinds of feedback controllers in terms of the LMIs, in which the latter tries to use less information about the delay. In order to make the LMIs less conservative, another two derived corollaries from the above controllers are provided, trying to make the so-called ellipsoids, in the insides of which the closed-loop system stability is guaranteed, as large as possible.
