ESPINOZA MORILLO, Milagros. FUZZY CONTROLLER DESIGN BASED ON THE DIAGRAM OF THE PARALLEL DISTRIBUTED COMPENSATOR (PDC). Rev. Fac. Ing. UCV [online]. 2011, vol.26, n.1, pp.95-105. ISSN 0798-4065.

A methodology for stabilization of non-linear systems is presented in this article. The fuzzy model proposed by Takagi- Sugeno (T-S), which shows the possibility to approximate non-linear systems by means of modeling using fuzzy logic techniques, assigning a linear equation to the consequent of each rule, is used. This characteristic allows that, for each linear subspace or model rule, a fuzzy controller can be derived that combines the action of the linear controllers of each rule. In the method of the parallel distributed compensator (PDC), a linear controller from each rule is obtained and the result is a fuzzy controller which is a fuzzy combination of the obtained controllers in each rule. Three examples of non linear systems that reach stability by means of the proposed method are presented
