ROBUST FUZZY CONTROL FOR CONTINUOUS PERTURBED TIME-DELAY AFFINE TAKAGI-SUGENO FUZZY MODELS

摘要

The stability analysis and controller synthesis methodology for a continuous perturbed time-delay affine (CPTDA) Takagi-Sugeno (T-S) fuzzy model is proposed in this paper. The CPTDA T-S fuzzy models include both linear nominal parts and uncertain parameters in each fuzzy rule. The proposed fuzzy control approach is developed based on an iterative linear matrix inequality (ILMI) algorithm to cope with the stability criteria and H_∞ performance constraints for the CPTDA T-S fuzzy models. Finally, a numerical simulation for the nonlinear inverted pendulum system is given to show the application and availability of the present design approach.
