摘要
This paper addresses local H-infinity control method to reject the disturbance for continuous-time T-S fuzzy models. Firstly, in order to overcome a few drawbacks of the previous results such as the special structure of free variable, redundant restrictive conditions and parameters, the time derivatives of the membership functions are analyzed and new linear matrix inequalities are obtained. Secondly, the H-infinity control theorem is obtained based on the new conditions. Finally, two examples are given to illustrate the effectiveness of the results.
