Abstract :
In this paper a method is presented for the stability evaluation of feedback control systems with a linear plant and a double input single output fuzzy logic controller. The method is based on the comparison between the nonlinear fuzzy logic feedback control system and its dual linear system with a conventional PD-controller. It is shown that the method is able to evaluate the regions of the database and the related rules that are undesirable from the stability point of view
