Eliminating the parameter-dependence of recent LMI results on controller design of descriptor systems

In this paper, a novel approach for controller design and H-infinity disturbance rejection of continuous- time Takagi-Sugeno descriptor models, is presented. This approach is based on a matrix transformation [1] which eliminates the parameter dependency of the linear matrix inequalities arising in some recent results. The proposed approach is an alternative to former results on the same subject ( includes and outperforms previous results or act as a complement of other approaches) as shown both theoretically and via illustrative examples.
