Abstract

We address the problem of tracking references generated by anexosystem when the plant is described by a Takagi-Sugeno (TS)fuzzy model. We propose the inclusion of a discontinuous term intothe control law to improve the performance of the controller, andin those terms, we give a numerical algorithm based on the use ofcomputer-aided design (CAD) tools, in order to reducesystematically the tracking error.
