T-S fuzzy controller for a class of systems with uncertainties and delay times

Abstract

This paper deals with stability analysis and control design for a class of delay-dependent nonlinear systems when using the T-S fuzzy model in consideration of uncertainties in the system. As a result, it arrives at a PDC controller in terms of the LMIs, which involves less information about the delay times. In order to make the LMIs less conservative, the controller also makes effort to use terms that usually is ignored but can help the LMIs be easily satisfied.
